Yertle

Yertle is a fictional turtle that appeared on the Netflix original series Stranger Things. He appeared in the third episode of season two titled "Chapter Three: The Pollywog".

In 1984, a teenage boy named Dustin Henderson owned a pet turtle that was named Yertle. Dustin had found what he believed to be a pollywog in the garbage can outside and brought it into his room. He temporarily "evicted" Yertle from his turtle tank to make a home for the pollywog. Only later did Dustin learn that this newfound pet was actually a creature from another dimension. Fortunately, Yertle appears to have avoided the creature's carnivorous appetite unscathed.
