Similes, kindergarten-style

I'm going through last year's kindergarten work by Hen. I imagine he won't care to see any of this when he's older, and he'll likely think I'm a bit of a nut for saving so much of it, but how can I get rid of this fantastic work product?

The kids in Hen's class read Crazy Like a Fox by Loreen Leedy to learn about similes. They then had to choose a word to complete the simile. Here are Hen's…

It's as soft as a jellyfish.

It's as tough as a rhino.

It's amazing like an electric eel.

And the one he made up all on his own…

As pokey as a pufferfish.

There are little pictures he drew for each one that are all awesome. Needless to say, this will be an assignment I keep at least for a little while.
