I was just thinking of the part in Onward where Tiny Barley needed to go to the bathroom and he was a holding a giant key (from his perspective) which is actually a normal sized bathroom key from Ian’s perspective
instead of a tiny sprite-sized key because thinking about it I’d like think that gas station would also have a tiny sprite sized restroom since the Pixie Dusters like to hang out there often so it’s kinda obvious that Tiny Barley should’ve been given a sprite sized bathroom key (which would’ve been really small from Ian’s perspective that he would gently hold in the palm of his hand before giving it to Barley) because really how the heck is Tiny Barley (or any of the Pixie Dusters for that matter) going to manage to use a giant toilet (from their perspective) to go to the bathroom without falling in? So it would make sense that if the gas station also had a sprite sized bathroom along with the normal sized bathroom then they would also have a sprite sized bathroom key along with the normal sized bathroom key
