Most of the Pixie Petal consists of leaves and flower-like shapes, the teeth of the Keyblade resemble the flower bulbs in Wonderland in Kingdom Hearts Re:Chain of Memories, the shaft is a flower stem and the Keychain token is a red feather, similar to the one on Peter Pan's hat.
The overall design of the Keyblade bears a resemblance to Marluxia's Dainty Bellflowers.
The Pixie Petal's name reflects the flowers in its design. Pixies, specifically Tinker Bell, are frequently referenced by Peter Pan.
