Info about The Secret Box and Tea at the Treedome
From The Lost Media Wiki
< SpongeBob SquarePants (partially lost deleted scenes of Nickelodeon animated series; 1999-present)
The secret box deleted scene is not real.
This is a clip from the original airing of the episode: https://vimeo.com/714875150
People who claim to have seen it in the original airing are most likely confusing it with this nickelodeon short, in which you see the embarrassing photo: https://www.youtube.com/watch?v=FZEIHzgeazY&ab_channel=NickRewind
Tea at the Treedome:
On the original airing, 5/1/99, and the First Season DVD, Tom Yasumi is credited. In a 1999 rerun, and on the Tales from the Deep DVD / Deep Sea Sillies VHS, Edgar Larrazábal is credited. It is unknown why each version seemed to be used interchangeably.
