"Personal Beast Pet!" (Give it a Read! You might like it)

[Karbuncle]

I like this idea... but would prefer smaller special pets... because I find large pets to be sort of annoying to fight with.

Thats a fine point! Its possible The Pets could be "Sized down". In Abyssea its been shown a lot of mobs can be "Bigged" and "Smalled". Tiny Malboros, Tiny Worms, Huge worms, etc. These pets could all be smaller forms of their real counter-parts
