Dang, it's been a while...Sorry bout that
Anne: Girl is right at your doorstep when she hears that you are sick. Will help you get things like food or water if you need it. In all honesty she will just hang out with you until you're better.
Sasha: If you are sick don't be trying to do anything. Sasha will deem herself your personal caretaker. None of your protest will stop her from getting you even the smallest things. Tbh it's just because she wants to spend time with you.
Marcy: Even before Amphibia she always had somewhat of a weak immune system. Because of this she can't really come and help you when you're sick. However she will spend the whole time you're sick texting and FaceTimeing you.
