Strategy:
The Tower Power Pokey is a multi-segmented boss with a spiky head. Jumping on its head will damage Mario. Your primary strategy revolves around the Fan Thing Sticker. Use the Fan to blow away its spiky head, making the entire boss vulnerable to Jump attacks.
Once its head is gone, unleash your most powerful Jump stickers. The Tower Power Pokey will eventually regrow its head, so you'll need to use the Fan again. Repeat this cycle: Fan, then Jump attacks. Its body segments can still attack, so keep your HP up with Super Mushrooms. If you run out of Fan stickers, you'll have a much harder time, so ensure you have at least one, preferably two, before the fight.
