I'm trying to breed a Gloom, which is a Grass/Poison type, with a Ditto. According to the wiki, I can use Red Mushroom and/or Hay Bale blocks for 3 points each. In a 9x9 default breeding area, I can fit 40 such blocks (40 going to cake/wool for the Ditto). That ought to be 40*3 = 120 points right? I should be getting a "grows rapidly every day!" message?
But I can only ever get the " a tiny bit more every day!" message.
The entire breeding area has a clear view of the sky and I've tried different proportions of Mushroom/Hay blocks. Is there something I'm missing?
Edit: Worth noting that the Ditto is happy as can be; with 35 cakes to drag its butt on it just barely makes it into the "rapidly every day!" tier.
