Solid Entities
Solid Entities gives most entities solid collision boxes, so they collide with blocks instead of passing through them.
What it does
Most entities that normally pass through blocks gain solid collision boxes under Solid Entities, which lets them collide with the terrain and with structures around them. Boats and shulker-style entities are the kind of mobs and vehicles that gain this behavior. Some entities, such as projectiles, keep their regular collision boxes to prevent issues. The mod is available for Fabric only, for 1.21.11, and runs on client and server, so the server and every player need it. It is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license and is not open source.

What the author says
Gives most entities solid collision boxes, meaning you can collide with them as if they were blocks. Think boats and shulkers. Some entities such as projectiles still have regular collision boxes to prevent issues.
