These episodes are reeealy cool the first one was a buuuunch of references to the old episodes like:Several of Squidward's self-portraits use the same style as ones seen in "Are You Happy Now?," "Out of the Picture," "Stuck on the Roof," "Chatterbox Gary," "The Night Patty," "Pat Hearts Squid," and "Dream Hoppers."
In the Squidward memory book, there are several references to past SpongeBob media.
The first page uses the baby Squidward design from "Goo Goo Gas" and the baby SpongeBob design from various episodes.
The second page is a reference to Kamp Koral: SpongeBob's Under Years, showing a picture of SpongeBob and Squidward at Kamp Koral.
The third page has a reference to The Patrick Star Show, where it shows SpongeBob and Squidward's designs.
The fourth page has a reference to the episode "Truth or Square," where it shows a picture of SpongeBob's house being sold, even having Squidward in the same hat from the scene and Incidental 49A in the background.
On the fifth page are two concept designs from the SpongeBob SquarePants pitch bible.
The sixth page has an image of SpongeBob standing in front of his Employee of the Month Awards on the Employee of the Month wall, referencing the episode "Employee of the Month."
The eighth page-and, to a lesser extent, the memory book as a whole-is similar to the one shown at the beginning of "Breath of Fresh Squidward."
It is also similar to a scene from "To SquarePants or Not to SquarePants.":credit to SpongeBob encyclopedia the other one was alright.
