Hot to the Touch

"Hot to the Touch" is the first episode of the fourth season of the American animated television series Adventure Time. The episode was written and storyboarded by Cole Sanchez and Rebecca Sugar, from a story by Patrick McHale, Kent Osborne, and Pendleton Ward. It originally aired on Cartoon Network on April 2, 2012. The episode serves as a direct continuation of the third season episode "Incendium".

The series follows the adventures of Finn (voiced by Jeremy Shada), a human boy, and his best friend and adoptive brother Jake (voiced by John DiMaggio), a dog with magical powers to change shape and grow and shrink at will. In this episode, Finn develops a crush on Flame Princess (voiced by Jessica DiCicco) and tries to get to know her, which proves difficult due to her destructive and uncontrollable power.

The episode was the first to be storyboarded by Sanchez and Sugar; Sugar's previous storyboard partner, Adam Muto, helped clean up the episode's drawings. Sugar wrote a short rap for the episode, rapped by Andy Milonakis. Originally, Sugar wanted Milonakis to write his own, but he felt the song was of quality and he wanted to rap Sugar's version. "Hot to the Touch" was seen by 2.655 million viewers and marked a significant increase in ratings for the series. It received largely positive critical reviews, with reviewers from both The A.V. Club and Slate applauding the episode's emotional range.
