The objective is to bump into other submarines. If the player gets stung by jellyfish three times, they will sink and it is game over. However, if the player gets eaten by a whale, it is an automatic game over.
Bikini Atoll can be briefly seen on the "choose your captain" screen.
In the game's files, the Bikini Atoll image is uncropped, revealing that it was taken from a television broadcast of the series when it was rated TV-Y. The reason the rating isn't TV-Y7 is because the game came out five years before the show was officially rated TV-Y7.
The green whale in this game differs from other whales seen in series.
Jellyfish won't go towards your sub if you do not shine your light on them.
When the sub makes too much contact with the whale, a red light goes off inside the sub to alert the player.
Inside the whale, along with the sub, tires can be seen.
