I'm able to fit all the monsters I have on all my habitats. For the Legendary monsters, I've created additional space to purchase additional monsters. Currently, I'm maxed out with 90 habitats. I'm currently expanding the ones I have to house my new monsters, but I honestly prefer to fill up my islands with all the monsters I choose to purchase. Is there an option to get more than 90 habitats? If yes, is there a specific level we have to get to to get more habitats?
