Dizziness.[Suggesting to @Spiffy]
Bonekid listened intently to the fight going on, trying desperately to watch the fight despite his short stature. When Chaka Ram finally exited the maze with Joanne, Bonekid got fired up again. This arena was MADE for him to work in, so he grabbed his sword and stood.
"I'm ready! Let me back in there! I'll give this masked gunner a run for his money!" Bonekid shouted before he took a few steps, tripping and falling over onto the ground immediately after. He was dizzy. When he wasn't carrying the sword, he could manage just fine, but now that he's carrying it everything was so much harder to do.
He looked over at Cedric after letting out a hearty sigh. "Captain Boone? Do you wanna show them what-for? I would, but I'm still in recovery from my fight."
