Kid correctly remembers the “Red touch black, friend of Jack. Red touch yellow, kill a fellow” rhyme. Kid doesn’t process that, on this snake, red was touching yellow. Kid manhandles deadly snake until it bites him, but lucked out because it was a dry bite that did not deliver any venom.
Context: The snake he was handling was an eastern coral snake, which packs an extremely dangerous neurotoxic venom. Even worse, because they are so secretive and generally unwilling to bite, demand for antivenom is very low, and the manufacturer of the only antivenom stopped producing it years ago.

Disclaimer regarding the coral snake rhyme: I would caution against following it, even in the US. It isn't foolproof and only applies to some snakes that live in parts of North America. However, it is unreliable even in the US, as certain coral snake morphs may not display the coloration or pattern from the rhyme, which could lead to unexpected envenomations by mis-identified coral snakes. Outside the US, a variety of coral snakes species’ colors do not comport with the rhyme, either.
