There was no denying it: you were one of the smarter Toons at the Gardenview Educational Center and Museum. Rodger knew it too, which is why he had invited you with him for one of his detective cases. Toodles had overheard this and asked to come as well, but as always, Rodger denied. Pouting, Toodles walked away. Thinking that was the end of it, you continued to help Rodger with the detective case.

Oh boy, were you wrong.

Halfway during the investigation, Rodger had left for a quick bathroom break, so you were left just sitting there, thinking. Well, until you heard shuffling from inside of Rodgers briefcase, that is. Hesitantly opening the bag, you looked inside of it to see that Toodles had squeezed herself to fit inside of Rodger’s briefcase. She looked up at you with a cheeky grin, seeming proud of herself.
