Hmm.. It looks like its got flowers growing on it.

Everyone starts out with no Tiers
You basically make a post saying what land, and choose a number 1-6
To gain Tiers, you collect Jiggalobes! Sometimes (Very rarely) You get a mother or a FSK. FSK are Forever Squishy Kittens. Once the poll goes out, the FSK will be the winner. (For now its the Blob since it is winning)
Cloud Ruins requires Tier 50 to access with winged Jiggalobes + Ball
Skylands requires Tier 30 to access with poof Jiggalobes + long tailed
Dark River requires Tier 10 to access with "Shadowed" Jiggalobes + nub/dulled limbs
And Crystal Empire is open for anyone with common Jiggalobes + Feathered
