Why doesn't Lutador like Vivo's name? Well, to pronounce 'V's, you have to put the bottom of your lip in the back of your mouth and feel your front teeth. It's likely that Lutador didn't want to feel his razor sharp fangs by saying Vivo's name.
No wonder Lutador is cranky about hating noises; snakes are supposed to be deaf! They can't hear sound but rather vibrations. Given Lutador's massive size, he's already unusual for a python, so it figures that he hates noise.
The Sand Dollars are not wrong in their assessment that Vivo needs to be quarantined and receive a checkup, but we soon realize that Gabi has a better measure of them as bullies when Gabi and Vivo fall off the bridge. Basic human decency would be making sure that Gabi and Vivo weren't hurt from the fall at that angle. They could also notify her mother about what happened, or the Coast Guard to get them off the barge safely Instead, the girls only care about the fact that "the kinkajou" is alone in the woods, with no thought for Gabi's safety. They also go on their own into the Evergaldes, without any adult supervision. All of these so-called knowledge leads to them nearly getting killed, and they're shamed when Gabi, who has no reason to save them, risks her life to rescue them from Lutador.
Fridge Horror
It's all but said that Andres's neighbors would take care of Vivo after Andres died. They probably feared the worst when he smuggled himself to travel with Gabi. Good thing Vivo had made his way to Marta, and Gabi probably posted an update about where Vivo was afterward.
Gabi visibly shrinks when trying to walk past the Sand Dollars to the bus. If they treat her that way when she's playing hooky on their bake sales, safe to say it was much worse when she actually wore the uniform.
