Same Pet For Multiple People:
If you and another person/friend would like the same pet follow these instructions...
1.) Have one of you retrieve the pet from the boat in the blacksmith area.
2.) After that go to the level where you would unlock that pet.
3.) Complete the level and have the other player retrieve the wanted pet.
*!* NOT RECOMMENED TO EXIT LEVEL EARLY*!*
If more than 2 players want the same pet repeat steps 1-3 with the other players.
