Solid Mobs

About

A Minecraft Fabric mod that gives entities collisions and interactions like blocks or boats already do.

Standing on a mob has you move with them, and you can hold crouch to stick to the mob and not fall off (as can happen with high lag).

Slimes can be set to be bouncy like slime blocks.

Mobs can be set to take a percentage of fall damage when fallen on.

The config("minecraft/config/solid_mobs.json") and command (/solid_mobs) allows tweaking of certain collisions, for example you can disable player collisions, pet collisions, & even tweak the amount of fall damage transferred to mobs being fallen onto.

For multiplayer this mod MUST be on both the server and client, (single player is fine) otherwise you will have stuttering and de-sync while colliding with mobs (you won't crash or any issue like that, but it is annoying).
