You’re gonna need two things:

1. Particle system to do the water ‘squirt’.

2. Decal to leave as the watermark.

First is pretty easy, plenty of free or cheap assets have water particle systems in them, but second, maybe not so easy.

I just had a look on the market, nothing to do with water decal. You might be able to use blood decal ( plenty of that of course ) and make it transparent.
