They Sent Us a Pie / Dust in the Wind When the Mechas notice a giant pie floating above Pretty Big City, they slice it up to share with all their friends. Pie for everyone! After the last slice is gone, the team learns that the pie was sent by some friendly aliens to stop an asteroid! Now it’s up to the Mechas to find something else to catch the asteroid. A quartet of singing stone heads are ready to perform at Big Old Boulder Museum … but they can’t stop sneezing! The Mechas have to go “Mecha Tiny” to figure out what’s causing the sneezing, and work together to solve the problem before the concert.
