This is a direct copy-paste from FAQ:
"Your Regard helps you evolve in the World Of Meeroos, earning you achievements and titles bestowed by the Meeroos. At certain Ranks, the ability to unlock certain items from the store occurs. You'll be able to purchase Meeroos content that isn't available to anyone but those who have reached that rank! The catalog of things available will always be growing."

I'm wonder what store this is refering to and what items/ranks there are. I've seen some meeroos playing with blocks or have other fun gadgets. Even if its just decorative items I want to know where they are please because I dont see anything at Twas.
