Captain Planet and the Planeteers - Season 1 Episode 10

Greedy garbageman Sly Sludge has found a get-rich-quick scheme where he rids the world of their trash by placing it on Laipuno Island – and claims he's reducing it with a machine whose blinding light causes it to be seen one minute and apparently in miniature proportion the next. The Planeteers go to investigate it and also meet Lenii, a local girl who works for him. When examining the machine when Sludge isn't around, Lenii is caught in it and they realize that the garbage isn't being shrunk but moved – to the island's volcano, which will soon erupt and bury the village in waste.
