Short #1: Wonder Girl is ready to help her sister Wonder Woman in the world of man, but her friends Batgirl and Supergirl are more interested in hijacking the fabled Invisible Jet.
Short #2: Poison Ivy is attacking the city, and Batgirl has to race across Gotham to meet up with her friends to fight the menace.
Short #3: Kara is grounded, but Batgirl and Wonder Girl convince her to sneak out to fight crime. She just has to get by her Cousin of Steel first.
Short #4: While fighting Cheetah, the girls argue whether or not "The Super Best Friends Forever" is a good name for their little team or not.
Short #5: The team tries to get in a fight with Solomon Grundy, but "SOLOMON GRUNDY NO FIGHT GIRLS!"
No relation to the Super Best Friends seen on South Park. Despite lasting for only five shorts, it has been wildly considered Too Good to Last. An online petition has been created to try to convince Cartoon Network to approve the shorts as an animated show for the network.
Mood Whiplash: The fourth short continues the series' silly vibe, until Supergirl accidentally throws her friends into a tree. Kara thinks she's severely injured them, gets down on her knees and tearfully apologizes for her Jerkass tendencies while dramatic music plays. Donna & Babs turn out to be alright and forgive her, and the short ends on a silly note... all in a minute & 15 seconds!
Most Common Superpower: Averted with the main three girls. Kara sort of has the MCS, but it fits her body type. Poison Ivy plays this trope straight.
Mundane Utility: Supergirl, Last Daughter of Krypton and posses all the powers of Superman, wants to use Wonder Woman's Invisible Jet... to cover Lex Luthor's base in toilet paper.
She's never been invisible before!
Batgirl, on the other hand, just wants to use the jet to get some burritos.
Stealth Pun: Wonder Girl is given a Brazilian accent... because she's one of the Amazons!
Over a year ago, the voice actress for Wonder Girl has confirmed on Twitter that the accent is really a bit of Mediterranean but she chose to throw in a Mexican accent. However, it does make sense that it could be Brazilian since she is notorious for her puns.
Supergirl wants to use Wonder Woman's invisible jet to cover Lex Luthor's base in toilet paper. As she's boarding the jet she's giggling evilly with an armful of toilet paper rolls.
Superman takes time out of preventing ongoing super-crimes to stop his younger cousin from skipping out on being grounded to go fight them.
Rousing Speech: Wonder Girl seems fond of giving these, particularly in the first and third shorts.
Thick-Line Animation: Carrying over from Lauren's previous show, characters in these shorts have colored outlines as opposed to the traditional black, though a little differently this time. Characters have a single color outline (Supergirl for example has a blue outline). Superman actually has the traditional black/dark gray.
Title Drop: in the fourth short, Batgirl thinks they should officially call themselves the SBFFs. Supergirl thinks its a stupid idea while Wonder Girl is just confused.
Wonder Girl: The Sebooofs? Supergirl: We are not calling ourselves the Super Best Friends Forever.
Visible Invisibility: Averted with Wonder Woman's Invisible Jet unlike most adaptions. In fact it even makes the people inside the jet invisible. All 3 girls don't seem to have trouble operating it and walking or flying around it, like it is visible.
Thanks to Cheated Angle, we haven't seen the inside yet, so it's possible the inside is all perfectly visible to the pilots and passengers.
