You could get her a LEGO set or a Blue-Ray of Spider-Man: No Way Home. There's 30 minutes of the three Peter Parkers. There's also a Spider-Verse artbook which is REALLY REALLY neat. Seeing concepts thrown out and all that.
Or if you want to go really above and beyond give her this:
This is a character that'll be showing up in the new Spider-Verse movie. It's from the 1977 Spider-Man Japanese show (the funny sentai one).
Would be really cool to have on a shelf and it could get her interested in the sequel. You could also take that as an advantage to spend time with her by watching the entire series on YouTube. For real, it's a trip lol.
