Adulting Dr. Doofenshmirtz & Isabella

[DR. DOOFENSHMIRTZ]
So you say you got a patch for leading people through a jungle?
But I've got a prescription for this anti-fungal

[ISABELLA, spoken]

[DR. DOOFENSHMIRTZ]

[ISABELLA]
Undecided whether I should feel disturbed or scared

[DR. DOOFENSHMIRTZ]

Got this ache in my shoulder
