Hanging bridges glitch?

Hey, saw this post while I was on break at work:

TikTok - Make Your Day

Does anyone know how to accomplish this or want to try to replicate it? OP isn't giving it away and I kinda want it.

If they're not giving away how to do it maybe it's a hacked island?

That's hacked
Not a glitch

People who hack their game can do so much
Even make everything water

But yeah, not a glitch
Full blown hack

Shame on anyone who does not tag with it being a hack
