Cyberchase: Lily Pad Bridge
The CyberSquad's only hope of escaping the island is a lily pad bridge that they find in a catastrophe kit. When they put the lily pad in the water, it replicates itself, creating two. Shortly after, they observe that the lily pads in the water replicate themselves, creating four lily pads. Inez estimates that they will need 128 lily pads to escape the island, and since the lily pads are doubing themselves, it won't take long for them to be able to escape.
