FOSS gamedev and creative worlds

Hi I Just Downloaded 0.4 Minetest And It's Working Great and all and i know it's still being developed but My
Main Question is Are there suppose to be animals in the game? Or is that part still be needed to update? cause
I unclick the Creative mode which should give me Survival mode right..? and then there is suppose to be animals and
i looked all over the island and there were none.. Am I suppose to download a Mob? If So Please Give me a link or something

you have to install the Animals mod. It adds cows, chickens, sheep, and others.
