High Quality Content by WIKIPEDIA articles! Avenger Penguins was an animated series produced by Cosgrove Hall Films in 1993, it was animated by Alfonso Productions, a Spanish based animation studio also responsible for bringing Cosgrove`s previous show Fantomcat to life. It aired largely on Children`s ITV and was originally to be called "Hell`s Penguins". It has the distinction of being the last Cosgrove Hall cartoon to be animated using hand painted animation cells, as all 2D animated series from the studio thereafter would use computers for the ink and paint process; with the animation drawings scanned and then digitally coloured.
