Pokémon Go Jellicent Female~ level 35! max wild leve! ! New ! fast trade!~~
Will trade you the one in screenshot.
Having the blue Frillish does NOT make this a registered trade. It will still be a special trade and 20,000 stardust is required ( unless you already have a pink female frillish)
Unregistered normal pokemon = immediate trade at 20,000 stardust.
Registered normal pokemon = immediate trade at 100 stardust each trade
