Sylvie & True by David McPhail
Sylvie is a bunny and True is a huge water snake--they're great friends who hang out together. The pictures are cute, there's one where the two go bowling and True gets a strike by stretching himself across the lane and knocking all the pins over with a bowling ball in his mouth. But it's not a foul because technically his shoes haven't passed the foul line.

I'm the Biggest Thing in the Ocean by Kevin Sherry
I love the illustrations in this book. The text is super simple, it's basically a giant blue squid who goes around to other sealife and points out how he's bigger. Then the squid gets swallowed by a whale, then it's like, "I'm the biggest thing in this whale." It's pretty funny, simple funny, but funny.

What Teachers Can't Do by Douglas Wood
The teacher here is a dinosaur who can't do lots of stuff and needs students to help. It's another simple, short book.
