Ruberto was just a regular wassie until he found a glowing, suspiciously radioactive birthday cake in an old pantry. He ate the whole thing (of course) and immediately got chonky, grew a mask, and sprouted a birthday hat that never falls off. Now, he’s the life of every party in Wassieville, showing up uninvited to sing off-key, summon confetti storms, and drum on his belly. Legend says Ruberto is secretly battling the “Great Anti-Fun Shadow,” a force trying to cancel birthdays forever. Until then, if you see a fat wassie in a birthday hat, hide your cake—he will eat it, but he’ll make your party unforgettable.
