Around 2007, Cartoon Network made a line of bouncy ball figures for FHFIM, EEnE, and BAM, the FHFIM and EEnE bouncy balls were released while the BAM ones were never released. All bouncy balls can be seen in the set image in the last photo. This Grim figure is a sample/ prototype that would have been used to go inside of the rubber ball, there is presumably a Billy one of these too but it has never been seen. The bouncy balls were canceled before being released and there are very few of these pre-production figures left, old factory stock. The figure does not stand independently which makes sense because he would have been encapsulated in a rubber sphere anyway. Extremely cool prototype, about 1" tall.
