These are the 4 World Rings from each world Dusk has to collect in order to be full angel. Dusk is given 3 animal forms for 3 of the worlds(besides the one on the bottom-right): weasel, meerkat, and dragon. Each with their own storylines, like Rikki's for example, and Dusk has to roleplay as them.

The 3 world rings(besides the yellow one with the rainbow diamonds) are being held by their world's evil villians. Dusk, with the help of the worlds' characters/friends, must go through the adventures and defeat the villians in order to retrieve the world rings.

The Ice Age ring(top-left):

The green ring with the snowflakes on it in the world of Ice Age. It's being held by one of these villians: either Rudy or Gutt. As Duke the Weasel, Dusk must defeat them in order to collect the world ring with the help of Buck, Elliot, or the herd.

The Spyro ring(top-right):

The purple ring with the gems and dragon eggs on it. It's being held by one of these villians: Reptor, Red(A Hero's Tail), etc. As Fyerwing, Dusk must defeat them in order to collect the ring with the help of Spyro or Cynder.

The Lion King ring(bottom-left):

The orange ring with the lion pawprints on it. It's being held by Scar or other lion villians. As Rikki, Dusk must collect the ring with the help of Simba, Timon, Pumbaa, or other allies.

The Angelic ring(bottom-right):

The yellow ring with the rainbow diamonds on it. Dusk can only go for this ring after collecting the other 3. With the other 3 rings, Dusk will be able to become half angel. After that, he must go on an adventure through the regular world to find his father's(the god Dawnolia) staff. After retrieving it, it will be turned into the Angelic ring.

After collecting all 4 World Rings, Dusk will then become full angel so he can be able to defeat Akurena once and for all.

The whole storyline is suppose to be Kingdom-Hearts-like and is half cartoon, half anime. Hope it's cool or good enough.^^;
