They also appeared on The Oprah Winfrey Show to warn about the dangers of chubby bunny. Fish's parents subsequently sued the school district, with the case eventually being settled out of court. She collapsed and was taken to Glenbrook Hospital, where she died a few hours later. It was to be supervised, but Casey and some of her friends began playing while the teacher was momentarily away. The contest was scheduled for the annual Care Fair held at Hoffman Elementary School in Chicago's North Shore area. On June 4, 1999, 12-year-old Catherine "Casey" Fish died after choking on four marshmallows while playing chubby bunny. Some variants of the game require the winner to actually ingest the marshmallows.Īt least two people have died of suffocation by choking on marshmallows. The winner of the game is the player who fits the most marshmallows into his or her mouth. After the penultimate player loses the game, the winning player might have to place one more marshmallow into his or her mouth and may have to state the phrase once more. The process continues until only one player remains. A player who fails to complete the phrase is eliminated from the game. Each successful player then adds an additional marshmallow to the ones already in his or her mouth and repeats the phrase. If they are able to state the whole phrase, usually in a comprehensible manner that the other participants wholly concur to, they pass that round. In the game, each participant usually places a marshmallow into their mouth and says 'chubby bunny'.
