Bats, BATS! BAAAATTSS!!
They can hang upside down too!
EDIT: OH GOD THE SOUNDS.
THEY CHANGED THE SOUNDS.
Each block has a new sound for placing instead of having one for breaking AND placing..
They sound so wrong, SO WRONG.
Placing wood sounds like someone's playing ping pong! And, they also added new footstep sounds to everything! Some of them aren't bad, but others are just... uughghhghghuhuhs..
Oh, and they added new mob sounds, new footstep sounds for those mobs, and the most ANNOYING SOUND EVER: EXP LEVEL UP SOUNDS. It plays EVERY SINGLE TIME you level up, and it's friggin annoying!
The sounds put a major damper on the 1.4 update for me, they're... so... Eugh...
Although, Lava sounds pretty awesome now.
