This is the only episode that contains a white cloud title card instead of small portable red television title card. This is also the first animated title card.
This is the last episode until DJ Lance's Super Music & Toy Room where DJ Lances asks “Can you help me?” and “Can we dance?” before the megamix, because starting with Season 2, DJ Lance would do recaps before the megamixes of each episode.
