Jeff the Landshark

This is Jeff the Landshark. Don't let his cuteness fool you (ignore the picture), as he is a deadly creature with immense power. He can level cities, move mountains, shape the oceans. You're a mom or dad walking your son around the city. Meanwhile, Jeff is just waddling past, minding his own business when your idiot child speaks up "What is that thing!?" Then all bets are off. Jeff stares at him for a second, then swallows him whole in the blink of an eye. Can you convince him to release your brainless child?
