... [Player],I've made a discovery!After studying these Firegrubs head,it looks like their bodies secrete some kind of flame-retardant jelly which keeps their hides safe while aflame.Very strange!I'm sure Chief MacGregor will be interested in the properties of this jelly.Thanks for helping the Mimicology Department,[player].Take this new sprocket.I think I managed a decent likeness of the Firegrub with my illustration.
