give me some form of good detail, I know you are capable of it lol.
>_>
I start by biting my thumb, to make it bleed. Once done, I write my name across the name column on the scroll.
Alright then. Let's do this!
Gamakiri
A simple toad like you mentioned. Although it doesn't have anything special for it to be summoned during the battles, I must say that it can perform genjutsu+oil+water techniques. I don't think any other toad can perform more than 2 techniques. So yes, its useful if you need to use a variety of techniques, but this toad isn't a battle grade summon. No weapons, not good with taijutsu or any physical combat.
Gamatatsu
Little bigger than a human? This must be the last time we saw this toad right? Because his brother was shown to be a fully grown up toad during the war lol. Apart from this, we have better options for water and taijutsu toads lol.
Gamachu
This toad can be helpful to store large items. Can store dead bodies for me, no? Besides, since it can perform kenjutsu and Taijutsu, it can pretty much be used for close range combat. And since its size it smaller, it can be used as an alternative for a clone.
