How to create paint splash effect?

Hi, I am very new to Godot and am trying to make a hidden object game similar to Lunosoft’s ‘Love is…’ (video for reference - Love is in small things gameplay - Made with Clipchamp_1736597547501.mp4 - Google Drive).

I would like to know if it is possible to create a similar paint-splashing animation when a hidden object is clicked. And how, if it indeed is possible. What makes recreating this especially hard for me are these two key factors:

1 - The paint splash on clicking a hidden object will NEVER paint over another hidden object.
2 - The paint splash’s size and shape is also random.

Thanks in advance
