These villagers are: kid cat who wears the number 1 helmet and shirt: agent s who wears the number 2 helmet and shirt: big top who wears the number 3 helmet and shirt, and finally, a new addition to new leaf, rocket wears the number 4 helmet and shirt.
Their birthdays also match the number on their shirt and helmet. For example, kid cats birthday is on August 1st and big tops birthday is October 3rd, matching the number on their shirt and helmet.
