Animal letter game

We are trying to get K to be more deliberate in identifying the letters with which animal names start with. We have started playing the animal letter game where K chooses a letter and we all try to name animals beginning with that same letter.

Here was a recent conversation in the car:

K: Let's name animals starting with the letter B
Me: baboon
K: Bat
B: My turn, my turn!
Me: (trying to be helpful) B, say "bear"
B: Dolphin ball!
