Joe and Blue invite the viewers to a neighborhood festival.
There's a big neighborhood festival being held in the Blue's Clues neighborhood. Everyone's excited about everything that's happening, although different things excite different characters. Magic is always a mainstay with Periwinkle and he has Joe & Blue play a Guess Who game and then provides Joe with a festival passport in which he can put stickers to represent the various events he's attended. By playing Shovel's beanbag toss game, we get another sticker, as well as a modeled look of the neighborhood. Marlee the librarian also has a game to play, a storybook game in which we match characters with the stories that they belong in. At the end of it all, the evening is capped off with a beautiful fireworks display.
This episode was dedicated to the memory of Fred Rogers, host of the long running series Mister Roger's Neighborhood from 1968-2001, shown on PBS. The episode was produced four months after his passing.
The dedication card before the closing credits read; "In Loving Memory of Fred Rogers. The neighborhood won't be the same without you." A short instrumental remix of Won't You Be My Neighbor (the Mister Roger's Neighborhood theme song) was also played during the dedication.
The trolley that also appears was also reminiscent of the one that appeared in the show.
This episode introduces a new format for the clues. They are magically animated onto Joe's notebook paper and they sing & talk. Joe is not shown drawing the clues and does not explain how to draw them. It wasn't put to permanent use just yet.
This new format however, received negative feedback from fans.
This was the second time that Blue didn't join in the Mail song. The first time it happened was in Blue's Big Costume Party.
In this episode, during the Mailtime Segment, there is a game of freeze dance. At one point, the music stops and there is a boy that is supposed to be frozen, but his visible reflection shows that he is still jumping up and down.
At the end of the letter, one of the boys gives Joe and Blue a stamp for the game to add to their passport, which is delivered through the letter.
When everyone is gathered for the fireworks, Periwinkle announces that there's five seconds until the fireworks. Then, Joe apparently freezes time and says that they should count down from five. Only once the countdown begins does time apparently start again.
When Joe was getting his notebook from Sidetable, the eggplant parmigiana Sidetable made was on top of the drawer. But when Joe started singing, suddenly, the phone was there for some reason
When Joe gets ready to draw the "Flashing Colors" clue, he first talks about how he's going to pull out his red crayon to draw the color red, but because of the new animation format, we don't hear him talk about or see him pulling out any of the other color crayons. In fact, at the rate by the animation proceeds, it seems like Joe never had time to pull out any of the other crayons at all.
This episode is available along with episodes of other Nick Jr. series on the compilation DVD "Nick Jr. Celebrates Spring!". It is also the last of the four episodes included on the Blue's Room DVD Fred's Birthday.
