the same key as the letter on the robot

"Left the key at the corner of State and Main"

PART ONE

1. Go left. Take the lighter from the boy.
2. Take the beehive from the tree. (As stupid as this would be in real life, apparently common sense doesn't apply here.)
3. Go left again. Aaaah scary thing in the cave we're all going to die.
4. Once you're done freaking out, click the beehive in your inventory and click the small branch sticking out of the tree.
5. Go "aww" at the cute little bear you freaked out over and watch it steal the beehive you worked so hard to get in that tree.
6. Click the lighter, then click on the cave. Take the radio, the skeleton leg, the book with the key, and the coins. Exit the cave. No, you don't have to put the lighter back in your inventory, it won't set anything on fire. (Denying the laws of physics!)
7. Go right twice so you are facing the gate again. Click the key in your inventory and unlock the gate. Holy crap we're in!

PART TWO
8. ... Or are we? Great, now you're stuck underwater. Click the tank or suffer a watery death like the last guy.
9. Go left and click on the odd vending machine. Click on the coin in your inventory and put it in the slot. Click the "He" (helium) button and take the tank. No, you can't buy anything else yet. No, it does not dispense candy. No, it will not be your friend.
10. Back up from the machine and go right twice so you are facing a small grotto with a dead fish and a chest in it. Click the skeleton leg and use it on the chest and BANG! it splits at the seams (once again, defying logic).
11. Go back to the vending machine, and repeat step 9, but pressing the C3H8 (propane) button. Take this tank as well and back up.
12. Click the propane tank in your inventory and click the not-pointy end of the hose. Click the lighter and (once again defying physics) light the end of your new blowtorch by clicking on the pointy end this time. Click your new weapon of doom so it goes into your inventory, then go right.
13. Click the blowtorch then click the grate. Truly free this time, right? Nope. Go right.
14. Click the helium tank and fill the octopus and watch the short cutscene. Woo, we're in the hotel! Done, right?

PART THREE

15. *evil cackle* Of course not! Click the red book the boy is reading, and read each section.
16. Go left, note the drawing on the wall, and open the parrot cage. Go ahead, he won't fly away.
17. Go right twice. Skipping a time consuming part of the game, click on the door and and click "Whisper", "Tall", and "Hello", then click the lever that is revealed. Otherwise, click the dining dish, click "TREBUH", go to the parrot room, feed it to the parrot, go back to the door, and put the parrot on the perch (yellow flagpole). Go back to the room with the annoying little boy who WON'T STOP BOUNCING ON THE BED and click on the grate on the floor behind the bird cage. Go back to the parrot and click him. He will say "Shout a short goodbye". Put in the password given above (if you read the book, blue parrots say the opposite of the adjectives they repeat) and click the lever.
18. Oh noes, what was that noise!? Go left. Click the arrows above and below the STOP buttons until all are orange eyes (remember the I.I.I. drawing?) and stare at the pretty lights for a second until that ugly Kim Possible ripoff with the horrible posture runs downstairs through the trapdoor.

PART FOUR

19. Oh, seems like this is another "your stupid family has gotten themselves into trouble again, help them" game. Go right and click the box on the wall with the blank pink keycard on it. Read the note and click the R on the second square of the second row from top left. (This part took me forever, I apologize x.x)
20. Go left twice and use the keycard on the box.
21. Oh noes arcade game! Quickly put your fingers on the ASD and JKL keys. To defeat them, press the letter on the approaching robot's chest when it flashes white. Quickly dispose of these easy adversaries (although it may take you a few tries, depending on how 1337 you are ^_~).
22. Take everything on the desk, then click the hammer and smash the glass. Get out of the room.
23. Oh sweet, they robots are dead! Click your family to free them. Follow them to the right.
24. Click the onion in your inventory and feed it to your family, turning their eyes red. Enjoy the explodey ending, and make fun of the stupid little game.
