Several miles downstream, Newt and Jacob washed ashore. Not only were they completely uninjured, they were only dampened with some token water that will disappear after a few shots. Hopefully, you'll forget that they're supposed to be wet by then.
"Follow me, I hear something," said Newt. He heroically climbed up a ledge while Jacob followed sidekickly. When they got to the top, they saw a giant, long-necked reptile stomping through the jungle.
"That's a dinosaur," said Jacob.
"It's not a dinosaur," Newt replied. "It's a Mokele-mbembe."
"Well, it looks like a dinosaur to me."
"Typical Muggle misconception," Newt muttered under his breath as he scrambled over the ledge. By the way, it turns out that Mokele-mbembes were involved in the Battle of Hogwarts even though this has literally never been mentioned before. This is canon now.
"All right, it's not a dinosaur," said Jacob as he made it over the ledge himself. "Now how exactly are we going to protect it from Grimmson?"
"How indeed," said a sinister voice. It was Grimmson pointing his wand at Newt and Jacob!
