Terror of the Black Knight / Battle of the Bands / The Halls of Time.
Episode Description:
Terror of the Black Knight: After being impressed by Irwin's realistic armor at the medieval fair, Billy wishes for a fancy armor too. Grim gives him the "Cursed Suit of the Black Knight". When Billy needs to go to the bathroom, the curse is revealed to be that the armor cannot be taken off until the person wearing it beats someone in a competition. Billy desperately tries to defeat other people at various contests, he but fails to come out victorious. He defeats Mandy at a breakdance contest in which Mandy decided not to participate, but he does not need to go to the bathroom anymore.
Battle of the Bands: Billy wants to join Sperg's garage band, "Purple Filth", and take part in the upcoming battle of the bands. After witnessing Grim's prowess with the electric guitar, Sperg invites Grim instead. Billy's dad, adopting the rock and roll persona of "Mogar", decides he and Billy should go to the contest to make a surprise appearance. Billy impresses the audience with his armpit sounds.
The Halls of Time: After missing on a school trip, Grim takes Billy, Mandy, and Irwin to the "Halls of Time" for a tour. There, Billy and Irwin mess the hourglasses that symbolize each person's lifespan. When they leave, they accidentally leave their own hourglasses, including Grim's, upside down, resulting in the group getting younger as time passes. Grim allows the kids to disappear by going before birth, but he cannot restore his own hourglass to its correct position and he disappears too.
