Pools of blood and splatter

Hello everyone.
So I decided to pull a prank on a friend of mine by making a 3D model of Dolan Duck and making it his background without him knowing it. However, I’m sort of new to Blender. I’m wanting to have him standing in a pool of blood, while there are blood splatters on him and the knife. How would I go about that? And also, if you have any ideas or tips for the model itself, please let me know.
Thank you.

Your best bet might be to try another section of the forum. Either modeling or simulation/particles.
