Grab the level on the official LittleBigPlanet website.
If there's a level creator in a game, you know someone is going to use it to recreate another game in a game. It's basically the one thing that is guaranteed for any game's level creator. The LittleBigPlanet series has an awesome level creator and someone used it to their advantage.
YouTuber Katapultoffel used LittleBigPlanet 3's level creator to recreate Dark Souls' Undead Asylum and it's pretty spot on, down to the Estus Flask. The creator even did a pretty great job with enemies and enemy placement, like the Asylum Demon.
The only issue with the Asylum Demon is that he isn't nearly as annoying in this version, but rolling away from him still works.
