Description: One of Tobirama's most diverse and unique techniques, Suiton: Senchinerupengin is a new take on suiton ninjutsu. With the rapid release and manipulation of suiton chakra, a suiton specialist will be able to form one hand seal and use the air's moisture to create two penguins of water, the same size of Shima and Fukasaku respectively, that fly around the user or stay on the user's shoulders. These penguins are special due to their signature techniques and composition, their names being Staryu and Starmie respectively.
Staryu - Staryu is a penguin made of water and through the rapid release and conversion of suiton chakra, has it's composition changed to that of a chakra draining mist. Due to Staryu's composition, it is able to create various ninja tools (kunai, shuriken, spears, swords, etc.) and shields of chakra draining mist up to short range of the user and control them with relative ease, however, once the tool is moved out of short range, it continues it's course at the same speed to wherever it was headed. This ability is b-ranked in power, but once the opponent is hit with this mist, they become significantly more sluggish due to chakra being drained from the opponent (speed drops by two ranks for two turns).
Starmie - Starmie is a penguin made of water and through the rapid release and conversion of suiton chakra, has it's composition changed to that of a crystalline water. Due to Starmie's composition, it is able to create various ninja tools (kunai, shuriken, spears, swords, etc.) and shields of crystalline water up to short range of the user and control them with relative ease, however, once the tool is moved out of short range, it continues it's course at the same speed to wherever it was headed. This ability is a-ranked in power, but has no other effects except for causing excess lacerations and having more power compared to regular suiton due to the crystalline like composition of said water, but still not enough to overcome it's elemental weaknesses.
Note: No S-rank or higher suiton for two turns after this jutsu is over
Note: Can only use suiton and non-elemental abilities whilst sustaining the penguins
Note: Can only be used by people who specialize in suiton
Note: Starmie and Staryu last a maximum four turns on the battlefield
Note: Only useable twice
Note: Can only be taught by Penguin.
I will basically summarize it for you.
If you have water as your specialty, you can use this jutsu. Form one hand seal and two penguins of different water (absorbing mist and crystal water) form on your shoulders (or around you). These penguins can form ninja tools and shields of water up to b-rank (for the mist, and when it hits the opponent, their speed drops two levels) and a-rank crystal water (overpowers regular suiton ninjutsu of the same rank). The tools can be controlled by the penguins up to short range, and once out of short range, it just continues on it's trajectory. You can only use suiton, ninjutsu, taijutsu, and genjutsu whilst the penguins are leeching off your chakra. You can use jutsu as the penguins use jutsu, much like kage bunshin. Overall, it is a neat tech.
