He-Man and the Masters of the Universe - Season 2 Episode 42 The Gambler

The Royal Family are holding a celebration with the Widgets, celebrating the completion of Man-At-Arms' new machine- the Coridite Reactor, which will generate electricity for all Eternians. Smudge, a Widget who has been given the job of guarding the reactor, becomes addicted to gambling with a showman called Melbrag at the ceremony. Melbrag tricks Smudge into gambling away some Coridite, and he flees with the sample, intending to sell it to Skeletor. When He-Man pursues Melbrag, he only tempts him even further, as Melbrag plans to capture He-Man, and deliver him to Skeletor for an even bigger payment!
