Meet the cast
LetterLoops is a little band of animal friends who help the youngest writers MAKE letters and numbers — the shaping you feel in your hand that helps reading grow. Squiggle the snail is the hero; the cast are Squiggle's friends. Everything is spoken and playful, with no wrong answers — a wobbly letter is just 'let's shape it together.'
