Getting boxed in by a bunch of shitty little animals feels awful, unfair, and unrealistic. Especially terrible in dungeons and getting trapped by a bunch of little green gelatins while mining.
Let us use the “Push” feature on wild animals. Make it require some skill, str/animal size determine stam loss, count as combat instigation, whatever. There’s no reason tiny animals like bats should form impassable walls for a big stronk hearthling.
