Larry the Lemon is a toy that D.W. owns. She gives it to Kate to play with to calm her down in "The Secret Life of Dogs and Babies". It makes another appearance in a box of toys in "Brain and the Time Capsule". Four years into the future, it appears again in Kate's possession in "D.W. and the Beastly Birthday".
The character is a parody of B1 and B2 of Bananas in Pajamas.
