The little critter was burying his nuts when he became lodged in the cover.
Concerned pedestrians alerted the emergency services when they noticed the small rodent in the middle of a Munich street in Germany.
Along with help from vets, the firefighters were able to release the creature with special metal cutting equipment.
They first tried to ease him out with soapy water but failed.
A spokesperson for the fire service said: "Apart from being a bit grumpy, which is understandable, he was fine and ran straight up the nearest tree.
"As it's autumn we think he'd been looking for places to bury his nuts but had taken a bit of a wrong turn."
