Did a double take with the mattress on my floor: This looks so much like the big, colored Pikachu on the bedsheet. It's looking up, standing instead of sitting, and raising the other hand, but the rest matches up well.

is it a female too? lulz

No, [the bedsheet] was from the R/B/Y era.

Yes, this Pikachu is a female, I can tell by the tail and having seen quite a bit of Pikachus in my time
