As for the Shuttle Loop stuff, it was indeed one of Wing Kirby's abilities from Kirby Super Star. One of the moves involved attacking really close to an enemy, which would make Kirby float them in the air. Attacking directly after that had Kirby do a sort of aerial loop-the loop backflip kind of thing, smacking the enemy around. That was the Shuttle Loop (heck, the move's description even says "throw [your enemies] for the Shuttle Loop!") So yeah, that's where Meta Knight's move comes from. Also, awsome music, and it's nice to have full clarification as to his moves' capabilities. Also, Drill Rush > Triple Rush.
