You've come to the right place if you like costume parties, or if you just enjoy scaring the living redstone outta your friends.
The title says most of it, but for those who don't read titles (about 1% of you...) I make skins based off of the mobs of Minecraft.
To download the picture, just right click, then click "Save Picture As...", then save where you like. After that, go to http://www.minecraft.net, (Log in!) , then go to "Preferences" at the top of the page. If you can't figure it out from there, then may Notch have mercy on your soul.
Enough talk, here's what you came for:
Contrary to popular belief:
-These skins are for your human avatar ONLY!
-You CAN'T lay eggs while using the chicken skin.
-The squid skin DOESN'T have infinite breath, or faster swimming.
-NO FREE BOW with the skeleton skin.
-While using the spider skin, you CAN'T shoot webs outta your fingers.
-NO shooting fireballs with the ghast skin.
