Ginger Soda is a soda created by the Mainland Gobbos. It only appears in Croc 2, and is one of the first items that Croc will see. The gobbos love it, and often profess their love of the way it fizzes up their noses.
In the Inca Village, the local burping champion drinks it to burp.
In the Sailor Village, the first Guardian, Soveena the Squid, attacks a port filled with Ginger Soda trying to steal it. So apparently the Gobbos aren't the only ones who like it, that stuff must be good.
