Client sided only mobs

[Xofol²]

Hey I'm new to forge modding and I would like to know how to render entities on the client only, like for exemple the client thinks there is a pig moving etc, it has ai and a hitbox but the server doesn’t have the entity, so like a real entity but only the client has it. Thanks in advance.

Like I want client sided entities, so no sync between client. I want each client to see their own thing, so if client 1 summons an entity on their client, client 2 and the server won’t know it even exists! Kinda how like ghost blocks are able to exist, I want my mob to exist on the client but intentionally.

So how can I do that? I lnow its possible.
