Season 5 Episode 9 and Episode 10 will be released as a 1-hour finale for the season.
The title of this episode is a play off the movie "Forgetting Sarah Marshall" (2008).
After fighting the Cookies, Morty pulls up a "Long List." It reads as follows:
- Water City
- Spiderbot
- Lava Crystal
- Tip jar
- Cookie ISIS (which Morty removes)
- Nuclear worm
- Return Conch
- Bean hordes
- Moon gremlin
On Morty's long list, one line reads, "Return Conch." A conch (pronounced konk) is a common name of a number of different medium-to-large-sized sea snails. Conch shells typically have a high spire and a noticeable siphonal canal (in other words, the shell comes to a noticeable point at both ends).
When Morty saves the Cookie planet, the item he removes from his to-do list "Long List" reads "Cookie ISIS" in the DVD version, but is censored to "Cookie Freedom" in some versions.
