Tarantulas

Tarantulas is Jon Arbuckle's mailman.

Rattrap constantly torments Tarantulas by ripping off his pants, leaving him shredded and scratched and playing practical jokes on him. Tarantulas perpetually tries to find a way to deliver the mail safely, rarely succeeding. Rattrap enjoys tormenting Tarantulas because he does not think dogs should have all the fun.

Tarantulas is the mailman for Optimus Primal's neighborhood because no one else will put up with Rattrap's tricks. In Mario, Sonic, and Mega Man at the Beast Machines, he takes advantage of this predicament by taking a two week vacation every year, getting a raise when returning early.
