Dude!
Where’s My Horse? Mod 1.16.5/ / 1.15.2 is a lightweight horse-finding mod for both Minecraft 1.12 and 1.14!
Eschewing the intricacies and preferences of former versions, you simply sneak-right-click on the planned monster (no more hostiles or tamed creatures owned by other players, and no villagers), then you can right-click anywhere to liquefy them!
Additionally, it includes a lightweight saddle recipe.
