According to her backcard story, Pineapple Paradise likes coming up with new ice cream flavors, which I'd think she'd sell too, and that's what I've had her do here. Card info:
My Pearly Pony Pineapple Paradise

1 Tuner + 1 or more non-Tuner monsters
If this card attacks, your opponent cannot activate Spell or Trap Cards until the end of the Damage Step. If this card attacks a monster with a higher level, it gains ATK equal to the attacked monster’s level x200.
