Racy Babies

Rasmussen & Soniyana are the fictional (non-canon) offspring of the threesome Iyana, Rasmus and Sonic the Hedgehog. They were introduced in a fanfiction by Ashley in a Skype group chat. Anthony and Iyana were also present in the chat.

Soniyana (left)
Soniyana has curly brown hair inherited from her half-father, Rasmus. She has the same medium brown skin-tone as her mother. The two also share a striking resemblance in facial features. She doesn't share any specific physical features with her other half-father, Sonic. She wears yellow bunny slippers and a pink onesie with a two piece diaper and bandeau set underneath.

Rasmussen (right)
Rasmussen resembles his half-father, Sonic, the most. He has the signature blue complexion, peach-colored features and anthropomorphic hedgehog head, complete with one double-pupil eyeball. His eyes are never focused due to a birth defect and therefor his vision is compromised. His black Afro hair is identical to his mother, Iyana's. He wears a zip-up blue onesie with one of the feet torn off and one yellow bunny slipper. He wears nothing underneath.

Abs
Both of the children's most impressive feature is their rock-hard abs. They obviously inherited them from their half-dad, Rasmus. They have to wear their onesies at all times when out in public to avoid being ostrichsized by the rest of humanity.
