The Tomy Sonic Water Fun Game was a prize that could be handed out for submissions to Speedlines in Sonic the Comic. The tubular capsule had to be filled with water before the player pushed a large button. This would send a model of Sonic the Hedgehog flying up as if he had just used a spring. The idea was to 'collect' a number of Power Rings and avoid a Buzz Bomber Badnik, although these couldn't really be implemented. An alternative design was featured in one issue, although the idea was mostly the same, with Sonic this time in a Spin Attack with the Green Hill Zone behind him.

The game became one of the comic's longest lasting prize. It replaced the Sonic 2 Badge in Issue 8 and remained until Issue 52, where it was replaced by the Highgrove Stationary Set.
