One: The Office and Environs
Get the light bulb from the cupboard, and the cash from the mousehole. Exit the office, and talk to the cat on the pavement outside. Use Max on him to obtain the orders.
Go to Snuckeys - one of them has a paper cup outside. Collect this. Inside, walk around until Max wants to go to the bathroom. Pick up the pecan candy (left hand row, top shelf) and talk to the attendant. Ask him to sell you the pecan candy. Then ask about the bathroom - Max will take the key and leave. Finish the conversation quickly, and go outside. Talk to Max before he re-enters the diner. Take the key from him.
Two: The Carnival
Use the orders on the fire-eater. After talking to the Kushmans, pick up the fur and the bottled severed hand in the hall of oddities. Exit by the rear door. In the Wak-a-Rat stall, get the fishbowl lens. Play Wak-a-Rat, take the prize (a torch) and combine it with the light-bulb. Ask the Cone of Tragedy operator if you can ride the Cone. After doing so, check your inventory. Ask the operator about your lost items - he will issue you with a claim ticket. Go to the Lost and Found tent. On leaving, examine the new item you have been given (the World of Fish magnet).
Next, ride the Tunnel of Love. Use the torch on the walls, and once it has been activated, you can use other items. When you approach the fusebox in the wall, use Max on it. In the tableau, examine the king's beard, and walk through the secret door. Talk to Doug, give him the pecan candy, and he will give you a crowbar to use on Trixie's trailer. Operate the Tunnel reset switch in the left hand wall. Exit Doug's den.
Use the crowbar on the trailer door. Inside, take the costume from the hope chest and examine the score card on the inside of the wardrobe door. It will point the way to the Gator Golf.
Head for Snuckey's, and ask the attendant to open the jar containing the severed hand.
Three: String, Fish and Alligators
Use the cablecar to reach the top of the Ball. Use the pillar in the centre of the area to operate the elevator. Once in the diner, talk to the tool-bender and ask him about the spanners ; he'll give you one. Get the wires and use them on the binoculars. Use the fishbowl lens on the binoculars.
Go to the World of Fish. Pick up the bucket of fish in front of the Bait stall. Use the spanner on the bolt holding up the plastic fish in the river. Get into the fish (use the mouth) and then use Max on it. The fish will come away from its moorings, and the fisherman will pull it up onto the net, where the helicopter will take you to the Ball of Twine. Once there, use Max on the dangling end of the twine.
Drive over to Gator Golf. Pick up the golf-ball retriever in the bin by the souvenir stall. Walk down to the course. After tangling with Bumpus, rescue Max by replacing the golf balls with the bucket of fish, and hitting the fish so that the alligators form a straight line across the middle of the range. Sam will go over to Max automatically. Use the glass door, then use the loose plank. Get the Sno Globe from the cavity within. Max will give you a second piece of Sasquatch fur.
Use the severed hand on the golf-ball retriever. Use the fish magnet on this new item. Go to the Ball of Twine museum, and use this 'reacher with magnet' on the exposed part of the Ball. Take the Mood Ring you find.
Four: The Vortex and Other Animals
Drive to the Mystery Vortex. Inside, use the mirror - you'll emerge in an underground cavern. Switch the red (left-hand) magnet on, then walk across to the right, past the blue magnet, and don't worry about the yellow magnet also. Return to the surface. You will be able to walk through the large orange door to the right of the room.
The above paragraph may need to be replaced by:
Switch the red magnet on (the extremities will be shining red light) and then switch the blue magnet on too (it will shine blue light). You are now surrounded by violet light. Exit through the mirror again, and now you will be able to open and walk through the violet door standing in the right part of the room. - Andrea Cecchetti.
Talk to Shuv-Oohl and give him the Mood Ring. He'll give you some advice about Frog Rock and a bottle of Mole Man Powder. Exit this room, go through the curtained entrance and get the fur from the floor of the Yeti attraction. Return to the Ball of Twine (diner) and use the binoculars. Use the wires on the binoculars. Control the speed of the binoculars by clicking the "switch"... When the rock between the two attractions mentioned by Shuv-Oohl appears, stop the visor spinning. The rock should be Frog Rock - if not, keep tracking around until another rock appears. When you locate Frog Rock, drive over to it.
Use the three pieces of Bigfoot hair and the bottle of Mole Man Powder on the rock. You will be shown the way to Bumpusville.
In the garden, use some money on the wishing well to the left of the screen. (Actually, this isn't an essential part of the solution, but it's so funny I just had to include it ! :-)) Enter the building, and go to the far left-hand room (the stage). After the performance, walk to the far right-hand room (the bedroom). Take the pillow from the truck-bed, and use the elongated hand on the large blue book on the shelf to remove it. Once the book has been read, locate the cleaning droid and operate it. Insert all the wires into their holes such that the map is totally green. The robot will trip the security field, and Lee-Harvey will go to find it. Go to the room he has just left (adjacent to the bedroom entrance) and use the VR machine. Get the sword, and use it on the centre of the dragon (This is quite tricky to get right, so you may have to repeat the trick with the robot several times.) If you kill it, grab the heart and it will turn into a key.
Go to the security field, use the key on the machine beside the door, and Bruno and Trixie will be released. They'll head off to the Jungle Fever party. Meanwhile, go to the room immediately to the right, and take the portrait of John Muir. Leave Bumpusville for the time being and trek over to Jungle Fever.
Six: Venues, Vegetables and Velociraptors
Talk to Evelyn Morrison (behind the counter) and read the brochures she gives you. These reveal the locations of the Mt.Rushmore Dinosaur Park and the Celebrity Vegetable attraction. Talk to the bigfoot bouncer and give him the rasp from the Snuckey's bathroom key.
Drive to the Celebrity Vegetable thing. Take a Conroy Bumpus eggplant from the box on the right, talk to the attendant and give her the picture of John Muir. Go over to the Dinosaur Park. Examine the two talking donosaurs. Use Max on the mammoth to obtain some sasquatch-like hair. Operate the tyrannosaurus voice and wait until the jaw is open...then do something else to halt its motion. (Use the eye icon, for example.) Use the twine on the jaw, then use Max on the twine. You'll end up with a dinosaur tooth.
Walk down to the Tar Pit, and beyond, to the Bungee entrance. Go up in the elevator, and use the Snuckey's cup on the elongated hand. Use the Bungee equipment (you'll have to do it twice; Sam's a craven coward!) and bounce down toward the Tar Pit. Pick up some tar with the elongated cup.
Exit the attraction. Return to the Celebrity Vegetable garden, and pick up the John Muir vegetable from the attendant. Back at Bumpusville, go to the bedroom and use the Bumpus eggplant on the toupee (This is a brilliant scene!) Use the tar and then the mammoth hair and the toupee on the stiltwalker's costume. Go back to Jungle Fever.
Seven: The Party, and what happened Next
In the lobby, use the fake Sasquatch costume you have just created. The bouncer will now let you through. Inside, take the wine bottle. Go to the kitchens (behind the stage, left of the screen in the background) and take the ice pick from the freezer window. Use the rear door and Bumpus will appear. To escape his clutches, remove the Bigfoot costume - Bumpus and Lee-Harvey will change in the freezer. Get Max to slam the door on them. You will be granted free run of the party by the Bigfoot Chief. When he's told you the story of the totems, go back to the Ball of Twine diner.
Get the tool-bender to twist the ice-pick for you, and use it on the wine bottle. This allows you to use the cork as a Sno Globe stopper. Return to the Mystery Vortex and use the Mini-Vortex. Within, use the Sno Globe and it will suck in some vortex energy. Return to the Totems. Walk to the right past Bruno, and then towards the rear of the scene. You should arrive in the Hot Tub area.
Use the Sno Globe, the dinosaur tooth, the John Muir gourd and the pillow with hair tonic on the tub in succession. I don't think it matters which order you do it in.
Sit back and watch the end sequence...!
