And They Named the FISH Skinny!

Here is a run down of what Mr. Beeks ate for lunch:
1 1/2 egg and cheese sandwiches
1/2 sloppy joe
1/2 muskmelon (minus three small spoonfuls for the rest of us)
2 cookies
and a glass of milk

So then....why does he look like this? (Just in case you can't distinguish the chubby from the skinny, Z is far left).
