Storyboards for this episode were shown on Facebook and Twitter by Mondo Media on March 26, 2012.
The episode was uploaded on YouTube on May 6, 2012.
When Mondo Media uploaded the Blurb for Nuttin' but the Tooth to YouTube, they put a binary code in the description. If you were to use a binary code translator, it would come out: The brand new Happy Tree Friends episode, Royal Flush, will be out at the end of April!
This is the first time Lammy's house is seen, though it only shows the interior of it.
Fliqpy and Giggles (the two characters who dated in On My Mind) are seen on the cards. Nutty is also seen on a card impaled to Giggles' head during her death.
If you listen closely, you can hear Lammy singing the the theme song during the credits.
This episode could further indicate that Mr. Pickels is a living creature, as he was able to kill Flaky, dispose of her corpse, get on the table, grab the attention and confusion of Giggles and come out of the vacuum cleaner without Lammy's involvement.
It is also interesting to note that Mr. Pickels actions in killing people happened only in his and Lammy's debut, where Lammy tried to stop, but somehow got involved in killing the characters, but in this episode Mr. Pickles' actions were clearly visible to the audience even when Lammy wasn't seeing him.
However, Lammy was around in all of his moving scenes.
Although Lammy mainly speaks her "Bahs" in this episode, her tone and expression depicts the words "What's taking her (Flaky)?" when she is curious on why Flaky is taking so much time in the bathroom.
Since Flaky was nervous at entering Lammy's house and the others felt confused about her presence, it is implied that Flaky wasn't invited to play, but decided to drop by or arrived there by coincidence.
This is the most recent appearance of Mr. Pickels as an living character if the featuring pop-up of All Work and No Play isn't counted.
This is the only time that Lammy and Mr. Pickels appear without Lumpy so far.
This is the first time we see Petunia's OCD outside of theTVseries. She was seen vacuuming a few bread crumbs off the table with a hand vacuum. Later, she screamed in horror as she saw an olive with a toothpick on the floor. Also, a more subtle reference, if one pays close attention, throughout the game, Petunia's chips are always arranged in perfect organized stacks while Giggles and Lammy's are stacked but falling over and Flaky's are just randomly thrown in front of here.
Though, it's a bit odd that the states of the other girls' chips don't seem to bother her at all.
The YouTube thumbnail spoils Flaky's death.
There is no dealer button to indicate who is the dealer when the characters are playing poker.
The characters who are playing poker did not raise any funds, as the middle of the table they are playing on has no poker chips. However the poker chips that are closer to them have decreased, so they might have did it offscreen.
This is the only episode where all the female main characters appear. (Flaky, Petunia, Giggles, and Lammy)
The name of this episode derives from "royal flush", which is the highest ranking standard poker hand. When the girls were playing poker, Petunia was seen with this set before Lammy brought the sandwiches.
The moral means to commit oneself to a course of action about which one is nervous.
The "Y U No Love Cro-Marmot" gag re-aired on the credits.
Ellen Connell's voice is sampled for Petunia.
Every sound Flaky makes after she finds Mr. Pickels in the toilet is sampled from her voice actress, Nica Lorber.
