ahhh agnes is in my campsite--really want her to replace simon and shes pretty cute also want her to piss off my sister
though i've been trying for ages to kick out simon for melba (´•̥ ᵔ •̥`) i really don't wanna resort to kicking out one of my other 9 villagers ( they're all my dreamies :c ) to have both of them >< --OR should i drop both of them
They're both solid choices! Maybe you could let Agnes replace Simon for a little while and then switch her out for Melba later on if you want, unless you think you'd become too attached to Agnes in that time?
Personally, I would go for Melba. She's pretty cute and I don't see enough people have her. I honestly think I would allow her on my island if I came across her.
I would only take Agnes If I needed an Uchi (Even though I prefer like 5 other uchi's first)
edit: Though I find the amusing option of dropping them both if you really can't pick. No one's a winner when everyone's a winner.
Both the villagers have different personality types so it would kind of depend on whether I'm missing a personality (I like to have all personalities on my Island and I'm currently missing a jock which is driving me bonkers).
I'd only pick Agnes if you need an uchi since it sounds like you prefer Melba. Your 10th villager doesn't ping often to move out so I'd go for someone you really want.
