A Boost Star and a Spring Star. In this form, a Spring Star appears inside a Boost Star when a Boost Star is used. Spring Stars are also found alone in other areas.

A Spring Star is a miniature Boost Star item found in the upcoming game Super Mario Galaxy. Like Boost Stars, these little things give Mario boosts into the air. However, these don't send Mario flying into space with power. They simple give him a small fling into the air to reach other things.

In some situations, there will be Spring Stars that will throw Mario up to a higher Boost Star, so he can use that to go to another planet; in other situations, the Spring Stars will bounce Mario to other nearby planets instead of farther away ones.

Spring Stars look a bit like Boost Stars, but with less sharp edges and a much smaller size. They do not have the orbs at their five ends like a Boost Star, so they are not resembled to a Sherrif's badge like their larger counterparts.

There is a giant planet-sized Spring Star visible in the distance in one of the gameplay footages from a trailer of Super Mario Galaxy; its use is not known.
