Her abilities could probably operate where they're one spell if you quickly tap B, or a charged version when you hold it down long enough.
Neutral B: Dagger Crystal Heart Attack (low damage, low knockback, good for opening for melee)
Up B: Bunny Rabbit Blast (single-direction leap in any direction)
Forward B: Narwhal Blast (short-range attack that severely damage shields and causes high knockback)
Down B: Syrup Tsunami Shockwave (short-range AoE that traps enemies in syrup)
Neutral B: Raspberry Panzerfaust (high-speed target seeking explosive that deals large damage)
Up B: Rainbow Glitter Unicorn Gnome Hat Kitty Bacon Hawaiian Nightmare (larger distance range, also deals damage to enemies nearby the start of the attack for whiffing)
Forward B: Warnicorn Stampede (long-range attack that sends warnicorns first, followed by Star traveling vertically to deal damage herself)
Down B: Turbo Nuclear Butterfly Blast (massive short-range AoE damage that's a guaranteed knockout from center stage if the enemy hit has at least 40% damage)
Final Smash being Butterfly Form where she doesn't have to charge up to get her Charged attacks while also giving her permanent super armor and flight.
