Rain World Duplicating a pearl via pup stomach
Quality isn't particularly good as this wasn't intentional and I recorded using instant replay. I may try to recreate it again and if I do this video might not exist anymore.
Sometimes you can't properly eat neuron flies while in 0g, and will regurgitate/swallow instead. Pups normally should not be able to regurgitate, but by somehow getting them into this state, they will do so. And it appears they inherit your stomach contents, so in this case my blue pearl was duplicated.
I searched around a bit and wasn't able to find this, so either I just couldn't find someone else's, or I'm the first to find it. Very cool.
