We've added this to the FTB server, so I thought I'd give people a quick rundown, as it includes some friendly and some dangerous mobs.
The official Mo Creatures site is here:
[1.4.7] Mo' Creatures - v4.5.1 with Elephants, Mammoths, Komodo Dragons, more ostriches, better Jellyfish! more fairy horses - Minecraft Forum
- Which gives you information on what the animals are, how to tame/breed them and what items they will drop etc.
There is also a Mo Creatures Wiki here - Dr. Zhark Mobs Wiki
Because Mo Creatures has a *LOT* of animals, we're not including them all on our server. Some animals and mobs will also spawn more than others.
I'll run through some of the mobs that you'll need to be aware of.
Animals you can ride
Horses, Flying Horses, Dolphins, Komodo Dragons
Animals that will attack you if you attack them or you get too close
Bears, Foxes, Jellyfish
Animals that will attack you if they see you
Komodo Dragons, Sharks, Big Cats (Lions/Panthers etc.), Rats, Polar Bears, Scorpion, Wraith, Werewolves.
So,.... the water is no longer always safe.... there may be sharks and jellyfish in the water. Sharks and Dolphins look similar so be careful. Sharks have a slanted nose, dolphins make dolphin squeaks.
Werewolves need to be killed with a gold sword (other swords need a lot of hits to do it)...
(I'll update this as I think of more)
