Greeda and Doc exchange glances. Greeda tosses Doc the knife and dashes into one of the rats to slam into it. Doc takes the knife and lunges at the rat trying to bit him.

Greeda tripped and hit the rat, but didn't hurt it. The second rat jumped on Greeda, trying to but through the armor, but can't do it.
Doc has much more success! He stabs the rat on him and it falls over dead with a squeak.
