Bolt & Buddies Add-on 1.21+

With the mod Bolt & Buddies, Mammoths and an unusual mob called Brammer will appear in Minecraft. Unfortunately, the author did not provide sufficient information about Mammoths. It is likely that they can be ridden and even equipped with a Carpet. However, there are a few interesting things about Brammer.
