Simples, these next two are just variations of summoning you currently already mastered, one is dropping gamahiro on your opponent, the other is a body slam summoning:
(Kuchiyose: Bodīsuramu no Jutsu) - Summoning: Body Slam Technique
Rank: B
Type: Offensive
Range: Short-Mid
Chakra cost: 20
Damage points: 40
Description: The user will quickly summon a generic, human sized, warrior toad that slams into the target dealing heavy damage. The toad is human sized and brings with him a katana. Upon being summoned the toad already carries momentum towards the target, making this a very fast technique. Once it hits the target or is countered, he disperses.
Note: Can only be summoned by signers of the Toad Contract
(Kuchiyose: Yatai Kuzushi no Jutsu) – Summoning: Food Cart Destroyer Technique
Rank: B
Type: Offensive
Range: Short – Long
Chakra cost: 20
Damage points: 40
Description: The user summons Gamahiro above the target, crushing whatever is beneath him when he falls to the ground.
Note: Must know Toad Summoning contract and counts as summoning Gamahiro into the field.
After those, you use a combination attack with gamatatsu that almost no one ever uses or like jiraiya you bind someone with flesh to trap them ect:
(Futon: Gamayudan) – Wind Release: Toad Oil Bullet
Rank: B
Type: Offensive
Range: Short – Long
Chakra cost: 20
Damage points: 40
Description: Wind Release: Toad Oil Bullet is a synchronized elemental combination technique with the user and Gamatatsu. It is a wind natured upgrade to Toad Oil Bullet technique. To set up for this technique the user must stand behind or atop Gamatatsu and focus their wind chakra whilst Gamatatsu focuses his chakra with oil in his mouth and then releases the oil combined with the user channelling the wind chakra through Gamatatsu, creating a powerful and fast stream of toad oil, which then spreads to cover a larger area but maintaining a powerful striking force due to the wind chakra.
Note: Can only be used with Gamatatsu and know toad-summoning contract.
(Gamaguchi Shibari) - Toad Mouth Binding
Rank: A
Type: Defense/Attack/Supplementary
Range: Short
Chakra Cost: 30
Damage Points: N/A
Description: The user summons the belly of a huge fire breathing toad that traps the opponent in its belly. The user can have the toad digest the enemy or capture him/her with the toads stomach wall, spill oil on the opponent and lastly blow out fire all while the opponent in inside the toad.
Note: If the opponent doesn't escape this jutsu before the toad digests him/her the match is automatically over since they are no longer alive. The opponent can escape only if their hands are free to make seals or they havent been caught by the toads stomach walls yet.
Note: Can only be summoned by signers of the Toad Contract
