I want to elaborate on this because I never went to Disney until I was an adult, and I thought this was actually kind of insane. There is clearly an entire park culture that doesn't speak to me at all, probably because I didn't experience it during my formative years. But I did go to some other amusement parks and never really saw anything like this. So Disney sells a shit ton of merchandise that's not really a character, or a franchise or anything, but for specific rides and things only at that specific park.
This is a ghost character in the famous Haunted Mansion ride

Apparel, housewares, and collectibles from the haunted mansion ride:

The pattern is the wallpaper in the ride. It's got a cool aesthetic, but I really don't get this. It's just a ride... It's kind of a cool ride, I guess? Although it's a famous ride, it's not just this one they do this for. Other rides have in-joke apparel referencing events that happen during the ride, or funko pops of characters from the ride. And they went even further and offer merchandise and women's apparel based on a specific
snack in the park that became popular:
The Disney girls eat this shit up and Disney responds in kind by providing endless amounts of meme merchandise that only really makes sense in the content of the park for them to buy to wear the next time they come to the park to shop and buy more stuff. It's seriously impressive. It's like it wasn't enough to push souvenirs for the park, they realized an opportunity to push them for every ride or random experience so you can properly "memorialize" the experiences you liked.
