I found this weird hidden car area while searching for strawberries:

It's right next to Granny's house:

Any idea why it's there?

INTRO CAR!!!! (if you go to the left at the start of the prologue in the normal game, you can find it)

For additional context, it's become a tradition in Celeste custom maps/mods to hide the Intro Car somewhere in the level. And you can find the Celeste 64 version of the regular Intro Car by turning around at the very beginning of the game.
