Belle Butterfly is one of the main protagonists in Baby Lamb & Friends.
Belle is an adorable yellow butterfly with red antennae, large yellow wings with green spots, and a purple abdomen. Her wings tend to act as extremities, despite real butterflies having legs.
Belle is, for the most part, very sweet and precious and has a heart for all of her friends. But she can be very adventurous, too, and is not afraid to stand up against anyone who messes with her or anyone she loves.
- Simon A. created her because he didn't want to make A.P. the only female character as part of the main 6.
- She is the only main character not based on a real-life toy Simon had.
- It is hinted that she may have a crush on Baby Lamb.
