Congratulations on the Chikorita, Flydro!
I've been SRing for a shiny Cyndaquil or Totodile (already have Bayleef) since before Christmas with no luck. I think for now I'm going to ditch that and just hunt in the wild. I have 6 Masterballs on-hand in case I find one. I'll be hunting on Route 210 (the southern portion) for now.
