Ivy is a total tomboy. She is confident, eager and very friendly, albeit in a rough way. She enjoys relaxing and hanging out with Sprig and is willing to jump into action if given the opportunity. Like most children however, she cares very much for her mother and when things get scary, is shown to cling to her like most children do.
Ivy Sundew is close in age to Sprig, but is slightly shorter and stouter than him. She is yellow with a light yellow underbelly and possess orange hair that stick out in tufts underneath her teal beanie. She wears a light blue shirt and denim dungarees to go along with them. She is barefoot with two toes, has three fingers and light violet tongue.
- It is implied in "Anne of the Year" that she has had a crush on Sprig for quite some time.
- Ivy seems to be the only true friend that Sprig has ever had. Though it can be argued that Maddie Flour is also a close friend.
