The Teleporter is a device created by S.T.A.R. Labs. It appeared in Diaper Madness.
It was created to teleport anyone anywhere just clicking the button. It only worked at short distances. The lab rats got loose and one them got near the teleporter. When it jumped on the button, it teleported both to Kevin's house. Kevin played with it for while, but he teleported into air and dropped it. It landed in Melanie's diaper and she teleported every time she sat.
