The Bleurghmuda Triangle is a location in Moshi Monsters, mentioned by Cap'n Buck after Gabby finds him in a pile of snow on Mount Sillimanjaro. It is a pun on the Bermuda Triangle, an undefined region in the Atlantic Ocean rumoured for causing many disappearances of aircraft and ships. As Buck is shown without his ship or crew, it is not really clear what happened to everyone, nor is it ever explained.
