I had selected 4 of my characters into my fursonas, it's my official and I already decide who.
The 4 that I selected.

Bondy Cesar (#4)

Oowy Loowy (#5)

Wong Poncho (#6)

Why I choose them? It's because I most active with them and addicted to them.
They're not my characters anymore, now they're my fursonas, the rest of them are just characters, I feel computable and satisfied adding any more of them.
