The document describes activities that a kindergarten in Bulgaria called "Latinka" did with the children on April 1st, International Day of Humor and Jokes. They played fun games like fishing in an inflatable pool, carrying eggs on spoons, popping balloons with hands, and catching bubbles. One game had children feeding stuffed animals with their eyes closed, which was judged by the cooks. The children were rewarded with sweets instead of points for the games. Laughter and joking around was encouraged for health. The kindergarten was participating in an Erasmus+ project called "Puppets mission: childhood without borders" from 2014 to 2016.
