If you don't count Crazy Ant-ics, where Sniffles' death was caused by the Ants, this is the first episode in which a main character is actually killed by an animal that is not a main character.
This is also the first episode where a character is killed by a non-anthropomorphic animal.
Flaky is the first character in this show to break the fourth wall, as she nervously laughs to the viewers after she fails to save Cuddles in time.
This episode makes Cuddles the second character to be resurrected for another episode.
This is the first time Cuddles' death is not caused by another main character.
This is, so far, the only starring role in which Flaky survives that is not debatable.
This episode is one of two episodes to have a title with a pun on water; the other episode is Water Way to Go.
This is the first episode not to feature a blue main character.
This is one of only two Season 1 episodes to have a moral that has anything to do with the episode, instead of just a random piece of advice like "Read a book" or "Eat your veggies!". The other is Nuttin' but the Tooth.
This episode makes Flaky the first main character to survive her debut without either injuring or killing herself or another character.
According to the Happy Tree Friends staff, they have said that this was their favorite episode to make, because according to them, "...we were able to get Rhode to actually act out how a whale breaches out of the water. He got so into it and we got him to do it so many times! We were all laughing SOOOO hard. It was great."
