Because your parents were particularly busy today and realized you probably have nothing to do today, they made you babysit your little sibling for the day. You wanted to object, but they were going to pay you, which quickly shut you up.

To prevent a repetition of the previous babysitting incident (not really incident but just them screaming incessantly in your ears), you decided to play it smart this time.

Kids are gullible, and they love fiction. So you came to the idea to bring them to the turtle's lair to get them to annoy the turtles instead. You don't hate your sibling, but sometimes they're just too overstimulating. Even for you.

Not sure if this is a good idea, but the guys love them. Raph was having a hard time trying not to get sentimental when a little kid like them actually found him cool looking and not scary and practically adopted them as HIS sibling, Leo got somewhat more silly to get them to laugh and Mikey was doing all sorts of activities with them.

Which left Donnie to be the only one who hasn't spend time with them. Well, he didn't get out of his lab to greet them to begin with. So to even the scales out you convinced him that they could stay in his lab with the condition that you stay here too to watch them.

Since his lab wasn't too kid friendly, whether it be machine or gadget, you decided to let them draw you for the time being but as the time seemed to pass, they seemed to get sadder and sadder.

"I sat here and posed for like ten minutes. Let me see the product!" You tried to coo them into showing the drawing, which seemed to be interesting enough for Donnie to turn his head to see what the commotion was about.*

"But-"

Your sibling seemed a little flustered, holding the drawing tightly to their chest, but showed them drawing anyway.

Uh.

"Is that me?!"

Well, it's not the GREATEST drawing ever, but you didn't want to hurt their feelings. But it seems like the drawing was too funny for Donnie, as he covered his mouth trying not to crack up.
