goshh the moveset she would have. so much potential.
just from came to my head:
Recovery: Flock Step bird (think megaman custom/snake's recovery)
Side B: Hole-In-One (golf club swing plus small golfball or large golfball depending on how fast)
Up Smash: Working Dough (can potentially double hit with smaller dough too)
Sneaky Spirits could be a final smash where you hit them with a bow at the end of the ghost's appearance like in the game, but if you miss it still does some knockback, damage, etc just not as strong)
Her various jabs and tilts could just be from her main game and tamborine.
