The Very Hungry Caterpillar was the first book we ever got to read in Kindergarten and I still adore it. I also loved Where The Wild Things Are, The Gruffalo, any of the Dr Seuss books and There's a Hippopotamus on our Roof Eating Cake. I don't know if this is technically a picture book but I also remember being obsessed with the Geronimo Stilton series when I was very young. :D
I forgot the name of it because it was sooooo long ago, but in kindergarten, there was a book like chocolate moose something. I forgot everything about that book including the name of it, except it involved a moose to an extent. I don't think i'll go crazy looking for the title etc.
EDIT: I think there was a piano in it too. I think the plot was super random.
Once you give a Pokemon a personality, you can't go back depending on the severity and purpose of it. It's no longer just a "pixel" in your box.
