The Raccoons - Season 1 - Eps 7: The Intruders!
While Cedric shows Ralph the inside of Cyril's new vault, the pigs mistake the two for intruders, and time-lock the vault, sealing Ralph and Cedric in 'til next Groundhog Day. Cyril tries everything he can to get them out, even the promise of a master security key hidden in the vault, but it seems hopeless, until Melissa, Bert, Broo, Sophia, and Schaeffer find out. Pretty soon, Cyril, Bert, Broo, and Melissa are dodging the extra precaution systems as they make their way underground to get to the vault.
