Webby playing the ukelele seems to pay homage to her Voice Actress Kate Micucci, a known ukelele player.
Webby must be able to read Japanese, because when she sees the ukulele game she immediately refers to it as, "Uke or Puke." The game is only labeled in Japanese, and is called, "ukurere ka gero ka." This is Japanese for, "Ukulele or Vomit?" but Webby could read it and immediately make it into a rhyming pun in English.
First appearance of Ma Beagle and 3 of the Beagle Boys in the new series, being Bigtime, Bouncer and (ironically for being skinny) Burger. The reason for the change in Rurger's s appearance and lack of voice in the series, is due to Burger's original characterization of being obsessed with food inappropriate for the reboot due to it being associated with outdated fat jokes which are considered too mean-spirited for the present modern children's shows.
Ma Beagle, matriarch of the Beagle Boys, is voiced by Margo Martindale, who previously played the matriarch of a crime family on Justified (2010).
Funzo's is a parody of the family fun centre Chuck E. Cheese's, which is a chain of American family fun centre's and restaurants.
