 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.
