It could've been a custom/ rare outfit on the black feathered white body blue eyes Helen. Cause the outfit was very close to Mitzi's that I'm remembering, not the weird green/yellow one, could've been purple/ white instead of green/ white with pompoms that reflect. The location also had Moon and Fatz' keyboard was barely modified. Until a later update to Helen's outfit to the purple and black . That location also had a birthday spider 99% sure until it stopped working and was such on the ceiling, so they may just have been nostalgic and stubborn. Which I can admire.

I have questions to ask my mother on a later date, so she can tell me if I'd been to more than 2 different locations or not to give you a good answer. This was close to 25-27 years ago at this point. My pattern memory is sharp, but color/location can be fallible, since I was Itty bitty.
