I'm curious about buying the Lost Penguin pet because I read that on the PC, you cant have the penguin out along with other pets. Does this apply to this pet as well on Xbox? Has anyone had this issue?

you can have it out with other pets....just can't have more than one penguin out at the same time.   The PC penguin was a free pet.  they wouldn't allow multiples of the same out.  they later gave a dodo pet.  which you could only have 1 dodo out at a time.  I believe all paid cash shop pets can have multiples out at once.

I have 4 penguins out right now.

Fishing reducing doesn't stack, everything else does.

Also you can mix it with dogs and birds and the fogan from my experience to include breeding non event pets.

Ok thank you so much, I wanted to buy it but wasnt sure
