Shape Up or Slip Out! is the fifth game in Al Lowe's Leisure Suit Larry series and again a classique point&click adventure.
All the events from the previous games are forgotten. Larry is single, and his goal is to capture the interest of various ladies. By sheer coincidence, Larry finds himself on a TV Game Show called "Stallions". He wins a weekend at the Spa Resort, La Costa Lotta. Naturally, there are some beautiful women in the spa who are just dreaming about such a wonderful, handsome man as Larry! Uh... or is it really so? It is the player's goal to find out!
