Cliffjumper (2001/2003/2007) A keychain version of Cliffjumper was released by Fun4All under license from Hasbro in the US in 2001. Though based on the original toy, this is an entirely new set of molds, with a number of small differences throughout (minor proportion differences and generally softer edges), but the most immediately obvious one is the small plastic ring added to the rear bumper to accommodate the chain.
