Goldfish and a limited-time snowman join the tank catalog

Changes

• Goldfish are now in the Creatures category of the tank catalog. Buy them with M coins and they swim around your tank. You can place up to 4.
• The catalog has a new Seasonal category. From December 1 to January 15, you can buy a limited-time snowman. Limited-time decorations you buy during their sale period stay yours afterward.
• New decorations can now appear in the catalog without updating the app.
