Crab Summon

Name: King Crab
Species: Cancer pagurus
Type: Arachnid
Rank: S
Elements: Water
Relation: N/A
Physical Traits: King Crab can burrow, moving underground as fast as if he were on land, with enough skill and control to choose of the tunnel closes behind him or remains open up to a hundred feet in distance.
He also has an incredibly thick carapace which is difficult to penetrate with all but the most powerful piercing or slicing attacks. Generally it requires an attack of S rank power to do damage to him, or two A rank attacks simultaneously.
He is capable of producing a powerful healing foam, which can cover a hundred square feet.  This foam heals up to B rank in injuries each turn.  If a ninja chooses to provide chakra to it, it can heal up the the rank in chakra provided for up to two turns after the chakra is supplied.  This foam can be produced twice a topic, and lasts four posts each time.
Description: King Crab is, as his name suggests, the king of crabs.  At least the intelligent species of them.  He is a hundred feet fall from his legs to the top of his head and has enormous claws, capable of crushing most things between them.  His personality is abrasive and gruff, but he is loyal to a fault.  He is surprisingly fast on his feet, and weighs in at nearly a solid ton, due to his heavy carapace and enormous size. A large portion of this weight is due to the muscle needed to propel such an enormous beast.

After further Review with another Mod i have found a few more errors

First of all, the app reads more like a technique than a summon this is more over the creature itself then what it can do.

The physical traits have several mentions of jutsu's that it can basically do for free. (King Crab can burrow, moving underground as fast as if he were on land, with enough skill and control to choose of the tunnel closes behind him or remains open up to a hundred feet in distance.) (He is capable of producing a powerful healing foam, which can cover a hundred square feet. This foam heals up to B rank in injuries each turn. If a ninja chooses to provide chakra to it, it can heal up the the rank in chakra provided for up to two turns after the chakra is supplied. This foam can be produced twice a topic, and lasts four posts each time.) These are jutsus and as such do not have to do with his physical traits

Also you need to make the foam into a jutsu instead of just a random ability and the burrowing would be hiding like a mole technique.

Also His personality is rather lacking, and he has no specs listed To use the foam and the burrowing he would need at least ninjutsu and medical.

Sorry for the inconvenience you can reach me when the edits are made but until then the app is Denied
