Mounts -
Backwards mount(the brown horse from the stable, but being ridden backwards).
Camo mount(a mount covered in grass/brush)
Centipede mount(I find the thought of oversized bugs mounts to be intriguing).
Dainty mount(a mount straight from a tea party. White color, white and pink bonet, maybe a tea cup in the saddle?)
Life guard mount(life preserver on the saddle, sunscreen on the nose, whistle around its neck? Feels like this fits well with oasis's theme).
Rainbow mount(a mount with a mane that changes colors. Not sure if gif mounts are possible.)
War mount(a mount with two sword ones on it's sides, perhaps the default shield on the saddle.)

Just a few ideas. I don't really have any ideas for morphs...
