Earplugs not included! Plus: Head to a rock concert with Luna Loud and... Myrtle?! Get ready to dare to interrupt Rosa as she cooks in her kitchen as Sergio and Lalo suffer a 'Snack Attack,' see what Cliff and Charles are really made of in one of Lisa's science experiments, or even more horrifying... try the food at Flip's 'convenience' store.
