Bananas in Pyjamas is an Australian children's television series that premiered on 20 July 1992 on ABC. It has since become syndicated in many countries, and dubbed into other languages. However only the animated series was dubbed and for some reason, Characters like Rat in the Hat, Topsy and Bernard's voices remain undubbed from the original. The show is on Amazon Prime in the UK but only in the original language and this dub never got released on any DVDs whatsoever adding to lost status.
