Love your drawing of the hat!
I don't know how many there are, but I see Cat in the Hat, the Lorax, and One Fish Two Fish Blue Fish Red Fish. (^_^)
The Cat in the Hat cheese art & Crinklebine the fish pick - the Lorax standing on his pepperoni truffula stumps - the Sneetches star crackers - One Fish, Two Fish, Red Fish, Blue Fish gummies - Green Eggs & Ham bento box :) Fun!
I don't know much about Seuss so I only know the Lorax and the Cat in the hat. But either way it's a cool lunch!
