from what I can understand, it sounds like one of his moves is to actually pull a pikmin from the ground, more than likely his Down B special move.
There's actually two more symbols missing, out of the 22 we "have" now

Symbol 21 has no character, but is used for a stage, the Pictochat one
Symbol 15 has no character, but is used for a stage, Animal crossing
and neither does symbol 5, but we all know that to be Captain Falcon's symbol, though right now it's there cause of Samurai Goroh
the only thing is, games with characters as assist trophies, that don't have playable characters, such as Dr. Wright or Knuckle Joe or Saki Amamiya, have the smash bros symbol for them. Basically I use this logic to tell me Captain Falcon, though not confirmed anywhere, is a playable character.
