Wait, how the
hell heck are you supposed to get this in Bowser's Inside Story if theres nothing that does it to you?
Hang on a minute...
Isn't it called POW-Up in Superstar Saga and Partners in Time? Not ATK-Up? I'm sure if you look at the various badge and clothing descriptions in Superstar Saga, it's referred to there as POW, and also the stat is called POWER when levelling up / viewing stats screen. I don't think it's actually called ATK-Up in any of these games - TTYD comes closest but doesn't actually use it spelt like that - it's more like "Charged! Attack power is now boosted!" and "Attack has increased!" Avengah 03:40, 22 August 2010 (UTC)
