• Ear Worm:
    • OH, use your imaginaaaaation, think of what you can do! Use your imaginaaaaaation, that's just the thing to doodley-do-do!
    • The Bookworm Bunch interstitial songs too. Ever thought you could never get simple children's songs such as "This Little Light of Mine" or "Skinnamarink" stuck in your head? Think again!
  • Ensemble Darkhorse:
    • FETCH! with Ruff Ruffman, Odd Squad, and Ready Jet Go!, oh so much. Each of these deal with a combination of either having a short run (Fetch! in particular), not getting promoted as often as other shows Adored by the Network, and/or breaking the mold in terms of PBS Kids shows enough that they garner a small but dedicated Periphery Demographic.
    • The Bookworm Bunch block also deserves special mention; it was placed on a once-a-week time slot (Saturday mornings) and only had a two-year run, but it won many people over due to its lineup of Canadian shows that arguably already fell under this trope to begin with. Despite only being a tertiary part of PBS Kids' history, many people look back on it very fondly.
  • Replacement Scrappy: The current PBS Kids mascots Dash and Dot, to those who grew up with the P-Pals (the old mascots). That said, The P-Pals only appeared in one bumper, and most people who watched PBS as children for a better part of the past two decades grew up with Dot and Dash.
    • Then, in 2013, Dot was given a redesign and paired with two new characters named Dee and Del. Dash now only appears in the circular PBS kids logo, upsetting people who miss just Dot and Dash being the focus of the bumpers.
  • The Scrappy: Caillou, Barney & Friends, and Teletubbies, due to the general idea that they pander to their audiences (as opposed to a show like Sesame Street which feels quite mature for a show intended for the same age range). Compared to most of the other shows that were featured on the block, these are generally hated due to a case of Tastes Like Diabetes, though of course there is some genuine reason passed around too (such as how Caillou is derided for teaching kids that whining will get you what you want, or that Teletubbies is full of nonsense speaking instead of actual dialogue). Either way, unlike other shows on the block where you will hear many openly admit how much they loved them as a kid, these tend to get swept under the rug for better or for worse.
  • What Do You Mean, It Wasn't Made on Drugs?:
    • The PBS Kids GO! branding was this in spades, with an odd mixture of live action elements and backdrops that look like they came out of an optical illusion or something.
    • To a much lesser extent, but some of the 2013 bumpers are also...Pretty bizarre. For example, there's one with Dee and Dot in a glass of lemonade...Only for a giant Del to start sipping it.
