Hypno based plane derg. Tailspin is always dormant within πie and when he wants to come out he hypnotizes the poor derg from the inside out and transforms. Tailspin will end up having the hypnotic eyes until Pie comes back and due to the nature of the tf/takeover Tailspin's also constantly (at least) semi-tranced out. Tailspin's belly is a hollow chamber for holding fuel or anything else that finds its way in there. The only digestion that occurs is the conversion of fuel into hypnotic fumes. Any solids come out unharmed.
