Misdirection plays a big role in the humor of these cartoons. An image might start off looking familiar, only to reveal a twist that flips your expectations upside down.

April Fools' cartoons often feature characters from popular culture, but with a twist. Imagine your favorite superhero doing something completely out of character, like knitting or baking, all in good fun.

Animals are frequent stars of April Fools cartoon pictures, often given human-like qualities or found in absurd situations that play off their natural behaviors in unexpected ways.

Technology and modern trends are not immune to the playful mockery of April Fools' cartoons, presenting gadgets and social media in a light that's both critical and comical.

Food is another common theme, where everyday items might be reimagined in bizarre ways, like a pizza with a topping of tiny umbrellas or a cake that looks exactly like a hamburger.

In the spirit of April Fools', some cartoons play with the format itself, such as comic strips that loop endlessly, leading readers in circles with no punchline in sight.

Interactive cartoons have gained popularity, where viewers can click or hover to reveal the joke, blending traditional art with digital innovation.

Environmental issues can also be tackled with humor, depicting a world where nature has the last laugh, offering a light-hearted commentary on serious topics.

Sports and recreation are not spared, with illustrations showing athletes in silly competitions or playing with equipment that defies physics, poking fun at the seriousness of competitive sports.

Transportation gets a whimsical makeover in some April Fools' cartoons, with vehicles that would be more at home in a fantasy novel or a child's imagination than on the street.
