IF- swell

"Some days you must learn a great deal. But you should also have days when you allow what is already in you to swell up and touch everything. If you never let that happen, then you just accumulate facts, and they begin to rattle around inside of you."

E.L. Konigsburg

Reading of "swell" as the new topic let me instantly think of a blowfish. But only the quotation that came along with it gave me the idea of a blowfish who was rattling around in his small illustration (or rather the illustration is rattling around the poor fish) and then blew up because he was so scared. In this case it's actually a porcupine pufferfish which doesn't really come in red, but it just had to be this color.
