While out exploring the galaxy with MOM, BUD's parental spaceship, she goes to pieces. Like, literally - MOM's all over the place. The positioning of that moon was terribly inconsiderate. Now her ship parts are scattered far and wide across an entire alien planet so rich in flora and fauna it would make even the most jaded galactic gardener's head spin. It's up to BUD to collect all her parts and get them back to the moon.
