Make sprites with physics behaviors stay "stuck" to each other

How do I...?
#1

I am trying to create the mechanics of an “Angry Birds” style game. To create the structures, I would like for convenience reasons that the blocks and bases could remain attached to each other with physics behavior applied to them.

Put another way, I need the blocks to be able to “stick” to each other, and be subject to the physics of the game without remaining static on the screen.

I am open to receive any answer that will help me. Thank you.

I haven’t watched it but there’s a tutorial

Hello, I really appreciate your suggestion, but it’s not what I’m looking for specifically. Although the video allows me to guide the bases of the project, I reiterate again that for convenience reasons I would like to build the structures by joining the blocks and figures together.

I would appreciate it if you could help me on that specific point. Thank you.
