Son of Nergal
While Billy and Mandy were playing in a park. Billy was playing on a swing and Mandy pushes it so hard that Billy goes high in the air with his swing which was tied with a rope. Meanwhile Grim comes and stands where Mandy was and gets hit by the swing Billy was riding on, which throws him into air.
He lands somewhere in Europe (possibly either Germany or Switzerland), and ends up with a paint bucket, which leads to Grim looking like a nun. After being taken to a nunnery and being shown a book, it turns out that the younger nuns think that Grim's a nun called "Sister Big Momma." At first, Grim tries explaining that he's not a nun--in fact, he's the exact opposite of a nun--but decides to pretend to be Sister Big Momma, and ends strongly bonding with the younger nuns and having a lot of fun with them.
Meanwhile, Billy and Mandy come by the nunnery to take Grim home. After the kids finally reveal to the nuns that Grim himself isn't actually a nun, the nuns, understandably, get mad at Grim for lying to them. Grim apologizes to the nuns for lying to them, but assures them that he loved spending time with them and had a lot of fun with them. The nuns forgive Grim and launch him, Billy and Mandy back home to Endsville.
