You know, I think you would be able to summon your own creatures to fight in Bundle arenas, like the one in the Sun Palace. For example, if I was bored, I would go to the arena, summon a creature, and fight it.
Like, I would fight a Rank 5 Shark Storm boss, a Rank 4 Wraith Death boss, a Rank 3 Skeleton Pirate Ice creature, or more!
