Consider Undersized functionality when entering Aquapolis (Or alternative means..)

[Tint]

[...] or making other Aquapolis exclusive rewards such as Orchestra Rolls, and minions available through alternative means such as the final tier of Eureka [...]

I like the undersized idea.

But putting the rewards from Aquapolis into Eureka would be a very short sighted solution, because Eureka will likely die out when 5.0 is released and the rewards will again be basically unobtainable.
