The Marsupilami triplets steal Hector's glasses to play Blind-marsus-bluff, and Hector blindly (once again, literal and in metaphor) blames the father, who ends up lured in with a marsu-call blown by Backalive in a marsupilami suit, and uses a game of hopscotch to place a trap on the unexpecting Mars. Backalive only needed the father as a test subject (and to get him out of the way) as he uses a simular trap-design to smuggle the triplets. Since Mars can't be heard in the seemingly-escape-proof glass, Hector needs a real eye-opener to save his friends and turn the tables on Backalive.
