Muffin builds her own amusement park, Muffinland! Samuel, Rudy and Mr Beakman are the first to try out the rides, but they all break. Muffin is disappointed, but the older birds explain to her that it takes more than one bird to build an amusement park, and all she needs to do is ask for help. So Muffin asks for help, and together the birds fix Muffinland and make it into a spectacular attraction for the whole community.

The community is throwing a fiesta and a mariachi band is supposed to show up and play. Unfortunately, the band can't make it and Mr Beakman announces they will have to cancel the party. Everyone is glum until Muffin picks up a pair of maracas and shakes them. That gives Samuel an idea! The kids decide to find instruments and make their own 3rd and Bird mariachi band.
