The name of the children's game of pumpkin hunting is as follows.

1. Pumpkin lanterns: During Halloween, people carve various shapes into pumpkins and place candles inside the pumpkins to make jack-o'-lanterns. Children’s pumpkin-hunting games can also be themed around jack-o’-lanterns, allowing children to try making their own jack-o’-lanterns.

2. Pumpkin War: This is a team game. Children can be divided into two teams and use pumpkins as weapons to attack and defend. The game rules can be adjusted according to the actual situation to increase the fun of the game.

3. Pumpkin treasure hunt: Hide some small gifts or candies in the pumpkins and let the children find them during the pumpkin hunting process to increase the fun of the game.
