Rick Roll.
Giant Enemy Crab.
Cthulhu.
EVERYTHING WITH GIANT!

I make ghostly giant beelike zombified things. _{I swear I've posted in the same topic before...}

Also, pregnant baby.

I made a level where you simply must get to the starite through a series of tunnels. But, the starite is guarded by a colossal invisible evil angry armed magic deadly invincible supersonic winged cthulu o.o
Also, along the way you meet a fertile woman So, so wrong

I like to make "fertile" people. Like "fertile clown". That way they just keep making babies over and over. >:3 I then proceed to freeze/burn/shrink/paralyze the babies.

@TeeJay Dang, you make me wish I still had that game. Hopefully Scribblenauts Remix comes out for 3DS.

i like putting the word awesome in front of things to make them run around creating explosives

Ridable. It allows you to ride on anything, meaning you can sit on top of a castle and make it move around.
Colossal. Makes everything huge.
Flying. Makes everything fly, which is epic. n_n
Neon colours. Because they're pretty. c:
Tame ridable flying cute colossal man-eating plant. Because it's epic to ride a huge man eating plant that can fly.
Transparent. Because I like spirits.

Rainbow things are awsome XD
BTW if you type in Ceiling Cat it works NO JOKE

Also I like making Sonic Ridable things. It's fun! n_n

I like making Manbearpig.

write "deadly", then write the name of a harmless object such as a book, then grab the deadly book and throw it at someone...

Also, write invincible magnetic ball, then make lots of then and put them near each other... 0_o

weaponized anything is cool. you can give them guns or whatever and use them.
Cool words:
Mecha
Gamer Sword (Cloud's sword)
Rail gun
Demolition man. (I pretend they're Halo Spartans)
LOL WUT (Just type it in)
Sky Cat

-Insane fast things are fun
-explosive things are quite enjoyable
-nuclear things will explode put them in things to leave a big surprise for friends for when they open them

-Have fun

I make tiny ridable flying pieces of paper, and become nearly invincible. I'm pretty sure your hitbox changes into that of the object your riding on, so your hitbox turns super tiny and you can fly through cracks in the wall etcetera. o_o

I also love making little tanks and stuff and making them fight... and screwing around with the object limit to glitch it to near unlimited... crashing the game.

I like the Time Machine. And I'm pretty sure you can make a working Arcade Machine. Can't you make your evil clone somehow, grab his book, and then use it to spawn random objects too? I haven't played in a long time.

...I am now going to go play Super Scribblenauts...

You know, when you use the Time Machine, sometimes you can go back to the first level of the first Scribblenauts game, and see yourself standing by that famous lone tree.Also, you can appear in an area just as you see yourself getting into the time machine to leave. It's quite entertaining! XD

@Teejay How do you do that? That is the last Starite I need for a medal.

Just keep randomly transporting to different times with the time machine. It takes takes some time and luck, but eventually instead of going to wherever you selected, you will go to that level instead.
