Pinkie Pie has "looney toons esque shennanigans" as her personal power set. With any other pony your argument might hold weight, but Pinkie Pie is explicitly called out in-universe as having strange powers and abilities, that even those who have magic codified to a science have trouble analyzing. While all ponies exhibit toonlike behavior from time to time, Pinkie Pie does itthat there is no way you can disregard what she does as one-off visual gags.She pops out of a bowl: www.youtube.com/watch?v=MmRYcc… She defies gravity in her very first encounter: www.youtube.com/watch?v=5rvjhB… Running from her? no matter that you're faster than her, she's already there: www.youtube.com/watch?v=Bps3A_… In the first episode: she weaponizes laughter and a song to dispell the scary faces created by Nightmare Moon.She is the Element of Laughter.She shakes the camera after freaking out discord www.youtube.com/watch?v=IF0i_7… After trixie hacked the flash editor with the alicorn amulet ( www.youtube.com/watch?v=cilfGI… ) to remove Pinkie's mouth, Pinkie: 1. manages to play a wind instrument despite having no mouth and being unable to talk. (Trixie is shocked by this, Twilight says 'oh that's just pinkie being Pinkie', indicating that the characters in universe are well aware of how physics defying this is) and 2. Tears her way into the void at the end of the episode, twilight opens her own portal and then fixes pinkie's mouth...Are you convinced that pinkie has toonforce yet? As pinkie has toonforce, "that's just an animation gag" is not a valid counterargument, because her power IS animation gags.
