World 1-5 has Mario and the others riding an orange dinosaur-like animal down a river. There are some fences in the way, but the only enemy in this stage are fish-like animals that can be bounced off of to reach greater heights. Coins can be collected by passing through rings and there are many split paths, some leading to secrets and others leading to Green Stars. The only really dangerous area is a series of windy turns about midway through the level, making it easy to fall off the course and into the pit below.
