The blocks are labeled with the letters A, B, C, and E. A green monster with horns and big eyes is standing next to the baby. The monster is holding a yellow object in its hand. The room has a beige couch and a staircase in the background. The baby and the monster seem to be having a conversation, with the monster making various facial expressions and gestures.
