The 1979 animated short subverts this. While it has been screened sporadically on Play School for over 3 decades (even during the run of the live-action adaptation), many toddlers would naturally think that the short was somehow inspired by the live-action series and not created before then. However, to the eyes of a preteen and older, it's plain to see in comparison to other animated shows on television nowadays that it was obviously created a long time ago.
A lot of the songs featured on the show, but one that particularly stands out comes from the episode "Radio Bananas" where the Bananas manage to run their own radio station at Rat's shop. An accident during one broadcast warrants an "oopsie", which accidentally finds its way onto the airwaves. The song that the Bananas make out of this will not leave your head.
Every song in the 1997 Bumping and-a Jumping special. EVERY. SINGLE. SONG.
Who could possibly forget the theme song!
"I'm a rat, I'm a rat, I'm a clever, clever, rat...", especially for the poor unfortunate viewers of USA Network's Cartoon Express or syndicated children's shows who had to deal with a Repeating Ad for a talking Rat In The Hat doll which sang that song. (It actually got one station in trouble with the FCC for showing it during an airing ofBananas. Make of that what you will.)
Uncanny Valley: Some might say the old series fell into this trope, but the new bananas have lips... and teeth... and eyebrows.
Not to mention Rat looks completely different from his earlier incarnation.
What Do You Mean, It Wasn't Made on Drugs?: More so in regard to the older suitmation adaptation. There's something slightly unsettling about seeing two giant sentient bananas wreaking havoc in a district populated by talking teddies and a giant talking purple rat.
