The two were still present in some near-final drafts made in the late 40s. While it is unknown where and when Alice would have encountered them, two songs were penned for the Mock Turtle at this point: Beautiful Soup in which he sang about some soup he made to the tune of "The Blue Danube" and "Lobster Quadrille" in which the Mock Turtle musically recited the poem of the same name while dancing with Alice, some lobsters, some oysters, and some baby turtles.
In the 1950s Jell-O commercial that they appeared in, the Gryphon and the Mock Turtle sat with Alice on the beach where the Mock Turtle expressed his discontent at having never studied cooking in school because it meant he would not be able to entertain with food. Alice then explained that he could simply entertain with Jell-O because it looked beautiful and he wouldn't have to cook it. At this realization, the Mock Turtle said he'd have a Jell-O party the next day, the invitation for which Alice and the Gryphon gratefully accepted.
- In the Little Golden Book of Alice in Wonderland, a cow-headed turtle creature (possibly the Mock Turtle) was among the creatures that appeared in the Pool of Tears.
