The second picture is an Echidna.
You will need to download the mesh made by Sim People and Me.
Then download the recolours as you choose. I've included their original Simlish recolours as well just in case you'd like them.
Simpeople and Me - for mesh and original Simlish recolours.
Pru - for requesting these and for the August Goodies event.
