The two Warner Brothers Yakko and Wakko and their Warner sister Dot had been (supposedly) created in the 1930's, but their cartoons were too screwy for the general public to handle. The three Warners were locked up in the studio water tower until they escaped in the 90's. There, they run wild, causing chaos everywhere!
This tv show contains 18 potentially triggering events.
Remaining locked in the Water Tower for 90+ years could be considered incarcerating the Warner Siblings depending on who you ask, but they aren't shown in any actual jail cells.
It's usually Buttons in the Buttons and Mindy shorts. One Slappy and Skippy short has Skippy inconsolable after watching a copyright free version of Bambi, and later in the same skit, Old Yeller.
lots of examples of people getting squished by anvils/oversized mallets due to the show's slapstick comedy, but there is no blood shown and no characters die or are seriously harmed from it.
No, but in one episode the Warner Siblings are the ghosts of Christmas Past (Wakko, who is 11), Christmas Present (Dot, who is 10), and Christmas Future (Yakko, who is 14).
There's a joke where Slappy says "I'll shoot myself" but it's in her typical cynical and sarcastic manner. The wording might still be alarming for sensitive viewers, though
Animaniacs is known for having a lot of innuendo, but otherwise there is no sexual content. The most explicit it gets is a silhouette of a character undressing.
