Lily loves brushing her teeth.
The reason she loves brushing her teeth so much is because Abby Cadabby is on her tooth paste.
You all already know that she loves Elmo, what you don’t know is that she also loves (LOVES) Abby.
She walks around the house shouting “Abby, Abby, Elmo!”.
Anyway, I guess she decided it was time to brush Elmo’s teeth also.
