There is a behind-the-scenes clip in the closing credits that displays how the models and graphics were done.
The closing credits are written as notations on various objects that Sir Lionel and Mr. Link use to plan their next adventure. At one point, Mr. Link drags a plate of cookies across the frame and eats one off-screen.
At the end of the credits, Mr. Link finishes off a drawing of himself and Sir Lionel smiling next to one another.
At the end of the closing credits, the Laika production logo displays tributes to its previous films (as the previous Laika film Kubo and the Two Strings (2016) did), but Mr Link himself joins the logo: he is seen walking through trees.
There is a Production Babies section
