|English anime||Watery Human Boulder|
|Anime||Naruto Episode #189|
After the user swallows a great amount of water to make themselves into a human-sized ball, they tuck their limbs inside their clothes and use chakra to propel themselves into a powerful roll. The added water gives the user extra weight, causing more damage to the opponent and area. This is an excellent technique to use against Water Release users as it not only nullifies their attack but also turns it against them.
