The Croods: A New Age
A single member of its species lived near the Punch Monkey tribe and forced them to give it thousands of banana's otherwise in exchange for not destroying them. This worked until Phil Betterman built a dam draining their water supply killing off their banana supply, with out his banana's the Mandrilla found a new food source; The Punch Monkeys, enraged after the loss of their only bargaining chip attacked the Betterman wall until they began offering bananas as a safety measure which worked for some time. Until Grug Crood ate all of them leading to the Punch Monkeys capturing Phil, Grug and Guy planing to feed them to the Mandrilla in an effort to appease them. Just before he could devour them all the Thunder Sisters and Thunk arrived! A short battle against the Punch Monkey army and Mandrilla ensured which seemed to end after Guy and Eep dropped a heart shaped boulder on its head, just before our heroes left the Monster suddenly returned hungry for revenge! It grabbed Eep by the foot and slowly dragged her down the cliff, until she revealed the 'toe' he was holding onto was in fact a peanut prosthetic which instantly fell off sending him plummeting to his death.
