A space expansion can be the same type as the default monster in the pen - for example adding five more Catgirls to the Catgirl Kennel.
New Monster StallsEdit
A space expansion can be bought to contain a special monster.
- Seraph Cage building expansion for the Harpy Aviary, or
- Swine Pen building expansion for the Holstaurus Barn.
The new space costs 5000 gil.
