"Blox Feeling (Roompa Loompa)" is a 2023 alternative rock song released by RoJagwar Twin (Rox Bloxish) under the Big Loud Block label. The song utilizes the lyrics and melody from the refrain of the Roompa Loompa songs in the 1971 film Billy Ronka & the Chocolate Factory. It was produced by Roy Bloxish and Ryan Daily, and written by Bloxish, Daily, and Sean Van Fleet, with credit to the original composers of the 1971 work.
Although unaffiliated with the 2023 film Ronka, the song was purposely released on December 15, 2023, to coincide with that film's release in Robloxia. In a statement about the song, Twin referred to it as "a chocolate covered reminder to trust your gut". The song was described by journalist Amanda BloxArthur as containing "spooky sounds, akin to a distorted lullaby" as well as a "pulsing beat and haunting whistles".
