vomiting my entrails = cool? Why Big D, what zany hijinks you are often up to!

Pufferfish can ingest a large amount of water in order to expand its perceived size to scare of predators. While drinking lots of water and being bloated isn't something cool, the idea of growing vastly larger than we usually are for a few seconds is (it would help get cats off trees, for example)

Then there's all the stuff insects can do -- lift several hundred times (or whatever) their mass, work in unison even when numbers involve the thousands, etc etc

:D
