Now what could possibly happen on a sunny day of fishing? Well, when Rubik tries to use magic to help reel in a big fish, things go awry. His magic beam goes astray, acciedentally snatching a treasure map from a couple of escaped criminals who are nearby, preparing to sail to a local island and retrieve the hidden loot. The map somehow ends up imprinted on Carlos's shirt and the two thug sailors capture the kids in order to recover the map. In the fray Rubik gets scrambled and is tossed out to sea, only to be resuced by a dolphin and a monkey (Yes, it's true, a monkey CAN solve a Rubik's Cube). Rubik, who has landed on the same island as his friends, the bad guys, and the treasure, tracks down the kids, and it's up the all of them to ruin the plans of the criminals. This is, of course, done with a little magic and the help of the island curse.
