The digester has a serated spine, and its lower legs are skinny. As can be guessed from its name, the digester is an eating-machine that attacks with acid. When it is hungry (which is pretty much always), it looks for a likely target in its forest or scrubland home, and then rushes forward, squirting a gout of acid from a tube in the top of its skull. The prey is effectively reduced to soup, and the Digester drinks. If the victim is not dead but the digester has used all its acid, it attacks with its legs until it can squirt acid again. When it does not wish to eat, which as said before is rarely, it lays down in the grass and avoids other creatures. Though sometimes solitary, they also sometimes group in packs of 3 to 6 individuals.
