Pogo has released new levels for Quinn's Aquarium today (The Deep Sea - Part 4)
You may not be able to see the new levels until you completed the previous ones. New levels are released on the second Tuesday of each month, so the next release will be available on August 9th.

Didn't they just release new levels for QA two days ago? And then 2 days before that?
Grrr
I've lost track! We're sure seeing a lot of it ...
