Hello everybody, i brought the perfect IV ditto from my last save and wanted to do some breeding because I am doing a mono water run. It could be an issue from me but I tried breeding with a shellos, and with oshawatt and neither are producing eggs. Is it a baby pokemon technically or a glitch or am I doing something wrong? I brought the ditto, lapras, tentacool, araquanid, carvahna, and pelliper with me thinking id be able to breed as soon as I got to route 5 with the mons from north of dresco town
