Wacky Packages are funny and silly trading cards that are like jokes. Each card has a picture of a real product, like a cereal box or a cleaning product, but the name and picture are changed to be funny, weird or wacky. The new name and picture makes it seem like the product is super crazy or gross.
For example, instead of a real cereal box for Lucky Charms, the Wacky Package card might show a box that says "Yucky Charms" with a picture of bugs and green slime inside.
These cards have been around for a really long time - even your parents probably had them when they were kids! They started in the 1960s and were really popular in the 70s and 80s. Now they come back every once in a while, and people still think they're really funny.
So, think of it like this - Wacky Packages are like a joke or a prank played on real products, and they're designed to make people laugh and have fun.
