In their thirties

A yellow, bug-like character wearing headphones and an orange shirt stands in front of a music classroom, initially looking concerned while holding a green device, then reacts with wide eyes and an open mouth, spreading his arms in surprise. The scene cuts to a wider view of the classroom, showing the character at a grand piano with other children playing instruments, including a girl on violin and a boy on drums, in front of a chalkboard with musical notes.
