The author-illustrator team who created Too Many Frogs! (2004) continues the fun in a picture book celebrating the excitement of a birthday party and confronting the letdown when it's over. As Froggie rushes through the forest to join Grandpa's birthday celebration, little listeners will imitate his actions and join in his deliciously nonsensical song: "Bah-Rummm-Tah-Rummmm, / Bah-Rummm-Tahtah-Tummmm." Froggie makes a costume, builds a stage, scribbles programs, and performs Grandpa's favorite song as a present, all to wild applause. Of course, when everything is over, Froggie doesn't want to say good-bye. The energetic, neon-colored acrylic, ink, and colored-pencil illustrations perfectly depict the wild celebration. Children will enjoy the uproar even as they recognize the anticlimax and the coziness of being alone with happy memories at bedtime. Hazel Rochman -- GoodReads
