This is the only set that I've found to be usefull for Wigglytuff.

Ivs: 160 Atk / 96 Def / 252 SpDef
Item: Focus sash

With some Spike support and Gravity in effect, your opponent will inevitable pull their hair out in pure frustration that such a Pokemon is causing them so much pain. Thoroughly tested, and I approve.
