LF:Loveball caterpie line FT: anything catchable in soul silver, some dream balls, breeding spitbacks

I thought i could catch a caterpie in a love ball on soul silver, but it turns out its a hg exclusive. I want to breed a shiny caterpie for my brother when he returns home from india on the 22nd, so I am trying to get this as soon as possible. Ivs/nature dont matter (although timid and decent ivs would help)

I can go catch something in soul silver (I only have 8 badges though), I have dream ball poochyena and kanga (and probably more, id have to check)

I have a lot of breeding spitbacks. Most will have decent ivs and egg moves.

I also have items. LMK what you are looking for!
