How can I find the collision position of two RigidBody2D?

Godot Version

Godot 4.2.2


I try to remake this game in godot?
Its name is Monkey Land.

And I’m stuck at making two same RigidBody2D collide and create a new bigger one at the collision location?
It also be great if there is a solution for the loosing part in this game(I haven’t thought about it???)

Have a look at RigidBody2D body_shape_entered() and Shape2D collide_and_get_contacts()

I use the rigidbody signal to make two shape disappear but still cannot understand the second method and how to use it.
Can you use it in an example or better in my problems it will be helpful
