Here's a little background in case you're interested! Collin MacCrae is Scottish and just arrived from Scotland to Roxi's city! He makes a bagpipe sound, and his sound is super loud, so loud that Roxi just thinks he's showing off and sees him as competition (she also tries to be louder than him with her electric guitar sound, but miserably fails). However, Collin, being friendly and humble, wants to be friends with her, and everyone else in the city too!
Also yeah, I doodled on my math notes in the 3rd and 4th slide 😅
