Face

Face was Nick Jr.'s mascot from September 1994 up to September 2004 when Piper replaced Face as the new host from 2004 up to 2007. He would often sing songs and announce what TV show was coming on next. On occasion, he would even interact with a character from a Nick Jr. show or short (usually from the one he's announcing), such as Blue and Periwinkle from Blue's Clues, the titular character from Little Bill, Bob from Bob the Builder (from offscreen), and even Philomena Fly from What's the Buzz with Philomena Fly. His signature phrase was not a sentence, but was actually his imitation trumpet noises, which he often made after mentioning the programming block's name ("Too too toot") usually followed by a giggle.

Face's last day on Nick Jr. aired on Sunday, September 12, 2004, alongside Maurice Sendak's Little Bear. After that, they showed a preview for Piper Possum followed by the final Nick Jr. bumper and Nickelodeon's Sunday schedule.

In September 2004, Face was replaced by Piper Possum as the Nick Jr. mascot. Before then, starting in September 2003, Face was redesigned with a new mouth, new eyes, new voice, and eyebrows. The redesign was not well-received and they returned to his old design shortly later. He is the only Nick Jr. mascot to exist on the block for more than three years, and actually still appears on a few of the Nick Jr. website's games. He also made a few appearances on a special New Year's-themed broadcast of The '90s Are All That with Stick Stickly on December 31, 2011. He also attempted to find the Easter Bunny during Easter 2016.

Trivia

 * Despite being one of the most well-known mascots of Nick Jr., some children, particularly those with autism, were scared of him growing up (sometimes especially after his removal), similar to that of DQ's commercial mascot from 2003 to 2011, a mouth (this might have been the case of triggering dreams during the night). The same conditions may also apply to other applications, such as the song "Stadium Rave" (featured in the SpongeBob SquarePants episode "Jellyfish Jam"), as well as THX's "Deep Note" audio logo used before the beginning of a film on certified home media (and even in a scene during the 2006 DreamWorks film, Over the Hedge).
 * Face, along with Stick Stickly, returned to The '90s are All That during New Year's Eve 2012. His appearances consisted of out-of-context clips that make him appear to be drunk or making off-color comments (e.g. "Yeah, grow a pair!").
 * After this, Face once again returned to NickSplat in Easter 2016; this time, his appearance consisted of clips that make him appear to ask viewers if they see an Easter Bunny
