Oh boy he really can not have this conversation right now. He tries all the same, though, his mouth pulling into a grimace as he tries to keep a hold on the squirming animal in his arms while he thinks.

"Well, uh-- a few different types of creature. There's the legged serpent, but that's not too dangerous. There's the, uh-- the rat king-- ow, shit!"

Okay, yeah, he definitely could not keep track of answering Natsu's question and holding onto the rat thing at the same time, given that the giant rodent had just managed to squirm free enough to sink its teeth into Ginko's arm. It takes the opportunity to leap free with an angry screech, scrambling away. Ginko swears again and takes off after it, his tail lashing.
