This jutsu is actually not a jutsu, but rather a technique, where the Romaji summoner and one reptile(group of reptiles) execute this technique by working together as the summoner would hold the enemy(ies) in one spot, usually with Sticky Slime Trap jutsu, while one or group of reptiles(usually crocodilians and snakes) would quickly eat them alive. Hence the name, 'Grub Dinner'. There was a man-eating turtles, tortoises, lizards, and salmanders, but most of them suffered a stomach problem, though some Romaji summoners use lizard with strong stomach. Snakes and crocodilians are usually 'used' to execute this technique along with their summoners. Like all other Reptile-Style jutsu, the users must be the Romaji summoners, in order to use it.
