Just a bunch of quick things from a bit ago. The idea was messing with the prospect of Meddy having some kind of loosely party-themed magic, though whether that's "canon" is up to the air. (or, you know, good mess around with at least)

Sorta elaborating on each:

Top left: Meddy lounging while holding a big bubble wand with a couple balloons tied to it, and a few bubbles next to them. (bubbles are totally loosely party-themed)
Top middle: Meddy holding a needle. "I can even use 1000 Needles! ...or close enough. (Because, you know, Pin The Tail On The Donkey and all)"
Top right: Meddy holding a bake they have summoned forth. "Immune to sugar overdose (but not to weight gain, which implies what you can imagine it does)"
Center: Meddy casting a magical fireworks rocket.
Middle right: Meddy using summoned ribbons to wrap around an Umbreon That Was Right There and turn them into a substitute doll (to stuff them into the gift box they are also holding on their other paw)
Bottom left: Meddy hiding behind a convenient bush while a "decoy" balloon floats in front of them.
Bottom middle: Meddy uses a Powered Up Swing against a newly-piñatafied opponent, peeking just below (with, yes, the drawback being the blindfold they get while doing that in order to get Max Effect)
Bottom right: Meddy, stuck as a Happy Birthday card after attempting to "fast" travel to another location by being mailed there. Written on its back: "Happy birthday! Have a real swell time today!! ps: can you turn me back, i tried to get here early by mailing myself like this but forgot how to get back to normal"
