Every second year since 2013, North Dakota resident Bill Fischer’s Chevrolet Avalanche gets filled with yellow-husked black walnuts by a neighborhood squirrel. This year, that squirrel was particularly busy.

After returning from a recent trip, Fischer opened up the hood of his Chevy and was presented with hundreds of walnuts. Clearing them out wasn’t an easy task and required him to remove the truck’s front fenders as well as the front bumper and headlights. He managed to fit seven six-gallon buckets with walnuts that were hoarded by this single squirrel.

Speaking with The Washington Post, Fischer said that as soon as walnuts start to fall to the ground around his truck, he knows he has to check the engine bay before driving it. He says the squirrel takes its walnuts through the rear of the pickup, carries then along the frame rails, and then places them in the engine bay and front fenders.

“I’ve got other vehicles that sit very close to that tree, and it’s always my truck,” Fischer told The Washington Post. “I’ve even parked purposely out on the street — as far away as I can from the walnut tree — and they still go find the Avalanche and hide them in there.”

Like he does every second year, Fischer is offering up the black walnuts for free to his Facebook friends. While the squirrel probably isn’t too happy to see its collection of nuts get removed, at least they’re not being wasted.
