This is just an AU pic of Wave, Tails, & Cream. In this AU, Tails and Cream were adopted by Storm and Wave when they were little infants from different families.
One day, Wave was so exhausted that she decided to sit onto the bean bag chair and rest upon it. A few seconds later, Tails and Cream came inside the bedroom, but didn't want to disturb Wave, but she smiled and asked them to come over to her and feel the triplet babies. They agreed and went over to Wave and she lifted her tank top a bit and motioned their hands to feel and listen to them. Happily, little Tails and Cream felt and listened to their stepmom's belly, hearing their triplet siblings move, squirm and kick inside Wave's belly. Tails' two tails began to spin excitedly as Cream smiles and listens to the heartbeats. This brought Wave so much joy, she began to tear up and asking them do they feel and hear the triplets.
