The girls at Mouse House are fired up for a new school semester. After their first day, Hoho tasks them to write a new song for their CD debut and the girls get closer during the process.
I know! What if we sing about
Mouse House for our debut song?
وجدتها! ماذا لو كان بيت الفئران 
موضوع أغنيتنا الأولى؟
Was haltet ihr davon, wenn es in unserem
ersten Lied um das Mäusehaus geht?
Dites, on pourrait faire une chanson
sur la Pension Souriceau !
Já sei! E se cantarmos sobre a Casa
Rato em nossa música de estreia?
