Because Tabuu knew that benefited you and I'm opposing you, he de-trophies me. We then rip open a hole to Subspace under your feet without warning, sufficiently disorienting you and allowing Tabuu to hit you with the Off Waves. Meanwhile, I claim the hill and seal the portal; Tabuu can't travel out of Subspace so he couldn't come after me if he tried, and you...Yhea. I also prepare a few countermeasures in case Tabuu tries to repeat our last trick on me.

MY HILL!!!
