Type disadvantage (Rowlet + other Pokemon)

(Although your Rowlet has a disadvantage against that Grimer, thankfully you had other Pokemon to back it up.)

"Dang, you're stronger than I thought," remarks Joseph, before handing you $384.

"Dang, this loss wasn't cool at all," murmurs Joseph to himself, "Maybe I should aim for being sexy instead... Anyways, I'll admit, I lost fair and square. I'll even give you a reward." (You obtained TM01 Work Up!)

"The thing about this TM, it teaches your Pokemon new techniques, hence why TM stands for Technical Machine. If it can't learn it, then oh well, sorry.". Just then you hear the school bell ring. The loudspeaker announces: "Attention, students, please escort [insert player name here] to the office on the second floor."

Lillie hears this and asks you, "Uh oh, what did you do?" You shrug and Joseph motions you to follow him.
