GabrielDropOutFTW124 decided to make Elena the host of the series because at the time when the first episode was produced, Eric (the voice traditionally used for Boris) was not working.
According to GabrielDropOutFTW124, the contestants who answer questions incorrectly will only get booed if their answer was too ridiculous.
As of November 2022, this is currently the longest-running GoAnimate-produced "Get Ungrounded Trivia" series.
