The Meaning of Life, the Universe, and Everything.
Axlotls are adorable! And axlotl-in-a-bucket is even cuter - caught one the other day with the intention of releasing it into my (underground) fishing lake, but ended up sticking it in an item frame over the bed in my village house instead.
Also like the glowsquids... And their ink - not especially useful for signs, but glowy item frames are *great* for map walls.
Haven't encountered any goats yet - need to explore my still-kind-of-new world a bit more, clearly.
