Kelp? Tuna?

What is this guy on about?

"I... I don't have any tuna."

This guy doesn't seem like a spirit, but there's definitely something coming off of him. He's just not sure what yet.

Whatever; before this guy changes his mind, he's going to grab Toge's hand.

He breathes heavily and coughs as he tries to catch his breath between the cold and getting pulled back up. He doesn't feel well, this cold is only making it worse. A doctor, medicine, even someplace warm would be great right now.
