Grim For a Day
The Halls of Time is the 23rd episode from season 2 of The Grim Adventures of Billy & Mandy.


After missing out 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, turns into a baby as he disappears too, leaving the episode as a cliffhanger.

The Halls of Time/Transcript


  • We've seen Grim be on the bus many times. But in the episode, "Halls of Time", the bus driver was afraid of him.
  • This is the first time Mandy cared when Irwin disappeared.
  • Mandy must be older than Billy and Irwin as they disappeared before she did.
  • The guy Billy and Irwin killed looked very similar to Maxwell Atoms, the show's creator.
  • Irwin disappeared without becoming a fetus.
  • The closeup of Irwin's hourglass shows "IRWN" written on the card, whereas all the background shots show "IRWIN".
  • This is first and only time Irwin's brother is seen in the show.
    • It is heavily implied that when Irwin throws his brother's hourglass away and we hear it shatter, Irwin's brother ceases to exist (which might explain why he is never mentioned again).
