The Tea Party (G1.5 TV episode, July 17^th 1992, 11 minutes)

Summary: While the girls try to decide whether to allow boys into their club, their stuff is stolen from the abandoned house they are using as a clubhouse.

Abandoned house being used as a playhouse by the young ponies. I remember doing that.

Gender segregation, more exaggerated than what's normal even in the 90's. This is another bit from when the writers were kids, likely in the 60's and 70's.

Elastics in their saddlebags? Doing what, exactly?

Rainbow Dash's ancestors?

Tails! What???? When did they gain this ability?

This isn't a move-in situation. This place needs a complete remodel.

Chestnut instead of cheese. Odd choice.

The little playhouse is very Victorian Gothic. I'm surprised that the girls didn't notice this being built, given the level of detail and amount of construction that would have been necessary.
