Two of the most obscurest Bust-A-Move/Puzzle Bobble characters you'll ever see!
These two are from Super Bust A Move 2 (PS2)
Puzzle Master Weepy is the Second boss in Story Mode, and also the weaker form.
Puzzle Master Smiley is the Last boss in Story Mode, and unlike Weepy, she's the stronger form.
Seriously though, next to nobody on the internet knows about these two, but, to be fair, Super-Bust A Move 2 is one of the most obscure games in the series, and these characters, to my knowledge, only appear in the PS2 version. I've seen nothing of them in the Gamecube or Gameboy versions.
