Help Wonder Red and the other Super Readers get into the Tooth Fairy's castle by completing the Clean Teeth Pledge, which is currently missing a letter. Practicing rhyming with -AY words, Wonder Red figures out the missing word and helps everyone to get into the castle. Working through the different -AY words that could be used, the group completes the Clean Teeth Pledge, which reads as 'Brush up, brush down, brush every way. Brush your teeth two times a day.'
