Narwhal is crossed out in title.

"Narwhal and Jelly are back and Narwhal has a new obsession . . . peanut butter! He's so obsessed he even wants to change his name to . . . that's right . . . Peanut Butter! Ever-sensible Jelly isn't so sure that's the best idea, but is all for Narwhal trying new things (instead of just eating waffles all the time, no matter how delicious waffles are). In this third book, Narwhal and Jelly star in three new stories about trying new things, favorite foods and accepting who we are. Always funny and never didactic, this underwater duo charms again through their powerful combination of positive thinking, imagination and joyfulness" -- Amazon.com.
