This is not a Bulbasaur

I really wanted to make littke comic strip about one scene what happened in our last session in Pokémon Tabletop. I told you earlier that I got an egg and it's mother was Ivysaur so we thought that of course there will come a baby Bulbasaur. Nurse Joy told us that Bulbasaur's egg usually hatches in 10 days and we heard from Morgan's mother that baby will be a girl. We didn't ask about specie because we did assume that we're gonna have Bulbasaur no matter what.
Well then... There was going the 7th day for the egg to hatch and our characters were surprised that the egg is hatching already. In the comic you can see what happened when the egg hatched...

You can imagine how shocked me and my friend was when we saw what hatched from the egg. I had really mixed feelings but now I can't be more happy about my baby girl Shroomish who I named Olivia <3 I think that I'd better have a  girl Shroomish than a boy Bulbasaur because if it was Bulbasaur baby it would have been boy.
I knew that Pokémon in the same egg group can breed but I still didn't think that opinion will be possible... How idiot am I?
