The episode is reminiscent of the Godzilla franchise. Ten months after this episode aired, the 50th anniversary film Godzilla: Final Wars (2004) was released in Japanese theaters.
This is the first episode of the anime in which a Trainer's Pokémon is enlarged, though this is not the first time a super-sized Pokémon was shown; the first time of that instance was in Giant Pokemon's Island!? (1997).
This title is a pun of the phrase "gulping it down."
