The day-care man says: Ah, it's you! Good to see you! Your DITTO and MAD-Z are doing just fine. The two seem to get along. GROVT... If we are looking after your Pokémon and notice one is holding an Egg, would you like me to contact you by phone? would that be all right? (now i can press yes or no)
if i press yes: you can leave it up to us! and pokemon you'd like to have raised you can leave in my wife's care.
If i press no: I see. Well, that's fine. Any Pokemon you'd like to have raised you can leave in my wife's care. (basically doing commercial for the day-care lol)
GROVT is my trainer name and MAD-Z is my steelix.
Im guessing you judge on if they get along or not.
