Wigglytuff's first appeared in the Kanto Grand Festival. It battled alongside Harley's Cacturne against May's Eevee and Munchlax, where Harley fully used its capability to expand its rubber-like body. Wigglytuff proved capable of moving in midair and held its own against Munchlax and Eevee after Cacturne was defeated. Wigglytuff was eventually defeated by May's Munchlax's Focus Punch, with the help of Eevee.
- Unlike other Wigglytuff Harley's has a purple glare across its face this may be to represent the evil personality of Harley's.
