===========================

A retelling of the original Discovery Kids' 2007 show, DinoSapien, set in the Equestria Girls universe along with elements of the IDW comics, with background characters leading the roles as well as updated paleontological science.

This takes place in the same Equestria Girls altered continuity as The Bridge after it's version of Rainbow Rocks, however that is not required reading as it deals with different characters in a remote area and will not star any of the kaiju roster.

It all began innocently enough. Mickey asked Donald and Goofy to help him find an anniversary gift for Minnie, and settled upon a gorgeous antique mirror.
Unknown to the unwitting buyers, there is another world just beyond the surface of the glass.
Through the magic mirror, all manner of villains, cutthroats and other evils have found their way in, and begun to wreak havoc to steal all the magic they can from the peaceful kingdom of Equestria.
In dire need of a hero, the source of Harmony in the kingdom sends for help, only for the saviors to be nothing more than a plucky little mouse, a hot-headed duck, and a dim-witted dog.
Will the three be able to save the kingdom of friendship? Only their adventure will tell as they journey through the magical kingdom, and uncover the mystery of the missing magic.

This story is a sequel to Sunset's Adventure in Skyrim

Life on Veldin, a planet in a remote corner of the Solana Galaxy, is becoming somewhat boring for Ratchet. Fortunately he's got two younger sisters that bring some excitement to his life, despite all three of them being different species. One of his sisters is a unicorn named Starlight Glimmer, while the other is a Cazar named Sunset Shimmer.

All Ratchet knows is that the three of them all arrived at the Veldin Orphanage together. One thing they can all agree on, however, is that they need to leave their home behind so that they can truly find their place in the galaxy.
