It's Valentine's Day in July, with Valentine-grams and a carnival. Mack must give Roger a private tour of Little Otter, when he wins a raffle. On the tour, they argue, flirt, and eventually succumb to their mutual attraction.

Camp Little Otter gets a record-breaking heat wave and everyone tries their best to keep cool. Buzz's 16th birthday is drawing near and he plans the greatest party the camp has ever seen in his cabin, or so he thinks. Sarah goes to Camp Ridgefield to borrow a generator and she meets her secret crush, Miguel Santos. Mack is surprised when her ex-husband gives Buzz the night vision goggles she had planned to give him for his birthday. Cole must help her come up a more-perfect birthday gift.
