Ziggy's home alone — Tiny Minion Ellie and the rest of the humans are out — which means it's time to test out the clean couch (the one she's not supposed to sit on). But comfort turns to crisis when something pointy jabs her from below: flat on one end, sharp on the other, and definitely not a snack. Undeterred, our not-quite-Batman detective sneaks onto Ellie's iPad (yes, she knows the password) to crack the case — uncovering pencil facts nobody asked for, from 16th-century graphite mines to a guy named Nicolas-Jacques Conté. Just as she's cracking the mystery wide open, the minions come home — and Ziggy has to hide the evidence fast. Some investigations end in triumph. This one ends in "feed me."
