* ActingForTwo: In ''King Cole's Party'', The actors who play Jack, Jill, Mary, and Little Boy Blue also play the children at the beginning and end of the video who are having the story read to them by their dad. [[spoiler: The actor who plays Old King Cole, also plays the dad who is reading the story to the children, but the dad's face is not shown until the end.]]
** In ''Marvelous Musical Mansion'', Uncle Rubato and Aunty Annabella share actors with Ruben and Rachel, their ancestors.
* {{Blooper}}: Due to being a local production, a few mistakes slip through the cracks.
** In ''The Best Christmas Ever!'', the kid in the wheelchair accidentally moves one of his legs in one shot.
** Also from ''The Best Christmas Ever!'', a crew member's hand is visible for a few frames after Poofer and the Smiths enter Santa's workshop.
** During "Risseldy Rosseldy" in ''Wee Sing in Sillyville'', one of the younger Bitty-Booties is slightly out of sync with the rest of the family's choreography.
* ColbertBump: The Tiddlebirds from ''Wee Sing in Sillyville'' gained a surprise leap in popularity courtesy of being a recurring element in the livestreams of Holly, one of the members in the [[WebVideo/WayneRadioTv Radio TV Solutions]] crew.
* CreatorBacklash: According to [[http://twitter.com/brothershageman/status/689458616517013504 this tweet]], Kevin Hageman (Peter) feels this way about ''Grandpa’s Magical Toys''.
* CrossDressingVoices: Wendy Westerwelle voices the male blackbird Jack in ''The Wee Sing Train''.
* TheDanza: Kaci Garcia as Casey in ''The Wee Sing Train''.
* DeletedScene: ''The Big Rock Candy Mountains'' have a couple jokes cut out, but seen on ''Wee Sing Favorites: Classic Songs for Kids''.
* DuelingWorks: With ''Series/{{Kidsongs}}''. Both franchises entered the home video market in 1985, and they continued well into the 1990s. Each have a similar concept of teaching AnAesop through music, though ''Wee Sing'' was more upfront about the lessons.
* HeAlsoDid:
** The actor playing the Crooked Man on ''King Cole's Party'' was Dallas [=McKennon=], the then-current voice of WesternAnimation/{{Gumby}} and the "voice" of Ripper Roo from ''VideoGame/CrashBandicoot'', as well as a regular voice actor for Disney.
** One of the associate producers for ''Grandpa's Magical Toys'' was the late claymation artist [[Creator/{{Laika}} Will Vinton]]. His wife, Susan Shadburne, directed both ''Grandpa's Magical Toys'' and ''King Cole's Party.''
* KeepCirculatingTheTapes: All of the videos between 1985 to 1994 have been released on DVD, but the videos that feature Singaling and Warbly haven't been released on DVD due to them being under Universal.
* NonSingingVoice: The kids' singing voices are dubbed on ''Grandpa's Magical Toys''.
* TheOtherDarrin: ''Wee Singdom'' replaces all but two of the returning characters' original actors, due to a move in filming locations from Portland to Los Angeles. Only Little Bunny Foo Foo and Sillywhim retain their original actors. Fortunately, the other characters are all heavily made up or else wear full-body suits, so the change of actors isn't too obvious, except for Trunky, (who was called Tusky in ''The Wee Sing Train'') whose voice is noticeably different.
* ProductionPosse: Due to the original videos being shot in Portland, Oregon, the city's famed community theater scene played a lot of the adult roles, some of whom showed up in more than one video. These include:
** Wendy Westerwelle, who played the Queen in ''King Cole's Party'', would later voice the male blackbird Jack in ''The Wee Sing Train''.
** Burl Ross, who played Little Bunny Foo Foo, played the hat rack in ''Marvelous Musical Mansion''.
** Vana O'Brien, who played both Aunty Annabella and Rachel in ''Marvelous Musical Mansion'', later voiced Old Grey Mare in ''The Wee Sing Train''.
* StarMakingRole: Annie from ''Wee Singdom'' is played by Nicolette Robinson. She got her acting career thanks to that video.
