The Missing Invitation

S1 E28: The team returns to the Musical Tree of Many Colors to visit their friend Butterfly (who they met as a baby caterpillar in episode 127). Just then, a Monarch Mail Carrier arrives with a big bag of mail. All the new young butterflies are invited to a big family party in a forest in Angangueo, Mexico (where Monarchs migrate in real life). The team’s invited too. So’s the viewer. But... Our friend Butterfly didn’t get an invitation!
