What about adding a tipped over cooler with ice you could make a whole cold biom, you could even add a rat boss that ate some of it, And mice around to fight to make a mice armor.

Grasshoppers would also be cool especially with their occasional flight

Also putting the cooler on the porch would give you all the room you need since it's pretty empty up there
