In 2005, a US version of the game began popping up on eBay and at small retailers, published by Treasure-regular Conspiracy Entertainment as Tiny Toon Adventures: Scary Dreams. Aside from the title screens and legal information, it was virtually unchanged from the European version of the game. Oddly enough, according to information on the box, copies of the game appear to have been produced in 2002 and shelved between then and the time it surfaced.
Another game (also developed by Treasure under the supervision of Hitmaker), Astro Boy: Omega Factor, used some gameplay ideas from this game, particularly regarding the way enemies could be knocked into each other.
