The little climbing robot B.U.D. returns in a new adventure across a vast, whimsical open planet. When his motherly spaceship M.O.M. crash-lands and scatters her parts all over the world and its moon, B.U.D. sets out to recover every piece and put her back together. Scaling towering plants, scanning strange floraforms with unusual powers, and gaining new abilities like a jetpack and gliding, the plucky robot explores the planet from its lowest valleys all the way up into space.
