That's none of your business! Since you've stirred up the wumpbee's nest, you and whiskers here need to get four of our people to new safe houses.”— Torn to Jak, Jak II
The wumpbee is an insect mentioned in Jak II. They were never actually seen, but probably resemble a wasp or hornet, having the word "bee" as part of its name, as well as Torn noting that they are aggressive if disturbed. As also mentioned by Torn, they make nests. Jak also makes reference to wumpbees while telling his younger self to stay away from them on his ninth birthday. The name is likely a portmanteau of the wumpa fruit from Naughty Dog's Crash Bandicoot series, and the bee.
