This mob was a request by . A platypus. It spawns in rivers. I actually had a lot of fun doing this. Its ridiculous. And it also makes you smile. Just by looking at it.
The Platypus has 6 hearts. If you feed it 1 raw fish or 1 raw lobster,* it'll be tamed. You can wear it on your head by right-clicking it. if worn, it'll grant you 10 more seconds of underwater breathing.
Alright. So then. Starting with top left, going clockwise. Platypus, 3/4 view from the right; front view; 3/4 view from the left; looking up at player, 3/4 view from right; looking right; swimming, looking at player from left, and standing.
*Yes, I said LOBSTER. And yes, thats right, I have another mob. Im going to post it soon. But for now, enjoy.
It'd be so cool if they could poison your enemies or something. I can see it now;"Go! Go, my venomous monotreme army! Today testificate village,tomorrow Minecraftia!"
