The bike allows you to travel further.

Look around one place for items and help for another.

Example: There's a fish in an aquarium with a key in the pet shop.

After you have repaired the bike, you can travel further by clicking on it.

I cannot find the third (=rightmost) item that is needed to activate the machine. I have found the other two. I haven't found any way of getting into AquaWorld either.

The television doesn't show anything but a dashed circle, though. The arrows on the remote control don't do anything. I don't know if there are supposed to be any clues there?

Says 411 on it?

In the classroom there is a sheet of paper w/math questions (the answers = locker combo)

found a gun thing and a remote, watched the tv, noted that I can't pull the plug in the bathroom, and found a safe in the basement.

there is a fishingpole. i just can't remember where it was. maybe the room with the wetsuits

it was in the green thing outside in the dump area!

it's in the tv dressing room. you'll need two cards

one is in a box in the eco storeroom<spoiler/>

the code for the basement safe is at the tv station, check all the boxes at the eco center to get access

pulled the plug, watched the tv, and I have plans, gun thing, and tv remote in my inventory. I don't know how to open basement safe, locker, or bedroom box.

turn the wheels on that big machine until it fills up with green liquid. i didn't turn them in any particular order though.
