- There are at least three different helicopters in the game: "Helicopter", "Attack Helicopter" and, yes, "Roflcopter", all with different sprites.
- "Neogaf" spawns a ball that can be used like a jetpack.
- Sadly, elements all spawn the same sprite and they don't react in any way (magnesium in water was already mentioned)
- The best way to get around is the Pterodactyl.
- Hoverboard and Hovercraft do not, in fact, hover. They exist, but they are completely useless.
- Put Maxwell on Rollerblades to disable the AI autojump
- Spawn a cloud and attach glue to create anchorpoints (for ropes etc.) wherever you like.
- Useful non-lethal guns I have found so far: Tranquilizer gun, Shrink ray, Freeze ray all disable creatures/people for a short while. As does feeding them large quantities of food.
- "Mind Control Device" is awesome.
- A bomb shelter does not protect you from the nuke
- Once I summoned as many parts of a dissected human being as I could. I was surprised at the number of organs that are present as unique sprites.
- "Liger" and "Tigon" are in the game.
- Speaking of which: Summon a tiger, shoot with mind control device, ride it. Spawn a cap, put it on. Put glue on the cap. Put a pole vertically onto the glue. Wait a few seconds and watch what happens.
- The most useful items for long and stable bridges I have found so far: "drawbridge" and "bridgeladder"
- "Black Hole" is a ridiculously overpowered item.
- Spawn two rabbits. See what happens.
- Grappling hook and Lasso are very useful.
- If anyone did not find this out yet: (Large) Fire and Air Vents are very useful too.
- The game does not recognize "assembly line". Use "conveyor belt".
- You can spawn differently coloured switches, but they seem to be completely useless.
- Speaking of which, has anyone found a way to remote control switches yet? Those tiny switches have three anchor points - One on the base, and one on each side of the lever. They have got to be good for something; but I have not managed to activate one of these switches yes without doing it myself.
- You can spawn a "walkthrough". Doesn't help you, though.
- Spawn the 5th Cell logo by typing "Fifth Cell". Yes, completely useless.
Level solutions:
- Puzzle 1-2: The first thing I did was to spawn a chameleon. Unfortunatly, chameleons in Scribblenauts can neither climb nor shoot with their tongue. Lame.
- Puzzle 1-5: I gave the thirsty guy vinegar. He drank it. It gave me the starite. However, in other levels people refuse to drink vinegar. Strange.
- Puzzle 3-9: Glued a fan and a sail to the iceberg, thus turning it into a boat. Alternative solution: Just attach the iceberg to the whale and then ride the whale.
- Puzzle 4-4: Spawned a superhero and attached him to the starite. Spawned a couple of additional enemies as "breadcrumb trail" back to maxwell. The superhero will fight his way from enemy to enemy back to maxwell, bringing the starite with hum (should work for other levels as well)
