Harley's Wigglytuff's first and so far its only appearance was in Thinning the Hoard!, where it was used 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. After learning from Lilian that Wigglytuff was the Balloon Pokémon, May quickly thought of a plan to utilize this to her advantage. Wigglytuff was eventually defeated by May's Munchlax's Focus Punch, with the help of Eevee.Wigglytuff was the only one of Harley's Pokémon to appear in May's flashback in A Full Course Tag Battle!.Harley's Wigglytuff is rather different from the other Pokémon of this species. It has a purple glare across its face, which is probably an attempt to make Wigglytuff fit the 'evil' stereotype of Harley's Pokémon.Wigglytuff's known moves are Body Slam and DoubleSlap.
