The name of the planet says it all: Raneforus is a planet which is all rain and little forest. It also contains geysers with rocks on it. This allows Jazz to bounce up to higher places.
Raneforus is inhabited by Monkeys which can be really annoying. There are also Big Hooters sitting on the trees, which can't hurt Jazz. With 50 shots they can be killed however, which gives 500 points.
The planet Raneforus is located in the Triangulum Galaxy.
