BIO Regrub was first discovered in New York City and is one of the more spirited Huffles currently residing in the HFH habitat. It came to the attention of The Helping Hand due to its intense love for burgers and other sandwiches—so much so that it developed a rather troublesome habit of snatching food straight from the plates of unsuspecting restaurant patrons. Nothing could stand between Regrub and its next meal.

Rescued in a back alley, Regrub was found waddling along, proudly clutching a stolen burger patty in its arms, wearing a floppy slice of lettuce as a cape and half a burger bun as a hat. Today, Regrub is thriving in the habitat, where it has access to all the burgers it could ever want—no sneaking required.
