"This diminutive fellow is a relative of the lobster. It's pincers are small, but distressingly powerful, wot? Indeed, it delights in a little pinchy-pinchy, eh wot? We'll take pains to ensure our mutual safety."

"You'll find these little fellows in many pots across the southlands, I imagine. I've personally never sampled one. They look rather... insect-ish. Blech."

"...I don't do particularly well when around crawfish. I mean, really. Look at it. It's like a wretched insect! And those legs... Did you notice all those wiggly legs? All the better to revolt me. Hoo, and the vulgar belly, all segmented and buglike. Absolutely abhorrent!"

It can be found in the middle-left tank in.

"These shrimp relatives are usually found in ponds and rivers, typically making them easy to catch. The reason for this strange habitat is that crawfish are plentiful and will eat just about anything. Eating plant material makes their bodies red, but only eating fish and meat will turn their bodies blue. A red color indicates they are eating a healthy and balanced diet, so red is the ideal for the species."

"Ohoo! So you have found a crawfish. Neither crab nor lobster, crawfish evolved in an interesting manner. Beware their fearsome pinchy pinchers! Behold their many legs! I say! It is a big bug-like, eh wot... The more I look at it, the more unsettled I feel... Let's be done with this and never speak of it again, shall we?"
