Please answer the following question: Generate a question about the following movie plot: Tinker Bell (Mae Whitman) is born from the first laugh of a baby, and is brought by the winds to Pixie Hollow (which is part of the island of Never Land). She learns that her talent is to be one of the tinkers, the fairies who make and fix things. Two other tinker fairies, Bobble (Rob Paulsen) and Clank (Jeff Bennett), teach her their craft, and tell her about the fairies who visit the mainland to bring each season. Tinker Bell is thrilled and cannot wait to go to the mainland for spring. While out working, she meets Silvermist (Lucy Liu), a water fairy; Rosetta (Kristin Chenoweth), a garden fairy; Iridessa (Raven-Symone), a light fairy; and Fawn (America Ferrera), an animal fairy. After meeting them, she notices Vidia (Pamela Adlon), a fast-flying fairy who immediately dislikes her because of her unusually strong talent. Vidia challenges her to prove she will be able to go to the mainland, and Tinker Bell creates several inventions, which she shows to the Minister of Spring (Steve Valentine).

On the beach, Tinker Bell finds parts of a music box and figures out how to put them together. Iridessa, Fawn, Silvermist, and Rosetta witness her doing this, then tell her that she was tinkering and that she should be proud of her talentif this is what she's good at, the mainland should not matter.
