I designed this watermelon slice for my 9yo Granddaughter.

She had specific requests: no eyelashes, blue glitter eyes, long skinny legs, furry yarn, arms.

Of course you can add eyelashes and not use arms or legs.
I also think it will look lovely in just plain red yarn.

Apart from the red you only need small amounts of pale green and dark green.

Safety eyes are used but embroider if for a child under 3.
