**Title:** "Among Us" Challenge with Mark
**Summary:**
* Mark participates in a family-friendly challenge inspired by the game "Among Us".
* The goal: Guess who among the hosts (Dan, Vadim, and another) is the "traitor" at increasing heights (3m, 5m, 7m, and 10m).
* Each incorrect guess results in a punishment instead of a prize (e.g., a unique Lego set).
* Mark faces various punishments for incorrect guesses, including a dramatic fall from 3m and a slap on the back from 7m.
* The final challenge at 10m offers a mysterious prize, potentially related to a new "Brawl" fighter, if Mark correctly identifies the traitor.
* **Spoiler Alert:** The summary doesn't reveal the outcome of the 10m challenge to keep the suspense.
