Just before the LaserTag round of Globnar, Blendin's score is 764. But after the Pines twins win the round, Blendin's score is 763.
When young Soos gets the postcard from his father, there are several continuity and factual errors.
1) The postman reads Soos's name from the picture side of the postcard. However, it's shown to have just the caption "Hello! From New Orleans" and a picture collage. 2) When the postman flips the card over, the top of the picture side is the same as the bottom of the text side. But when Soos handles and flips the card over, the two sides align top-to-top. 3) The text side, which on real postcards is divided in two into a letter side and an address side. But this postcard simply has the text of Soos's father's note, no address information at all.

When young Soos is depressed and sitting alone in his bedroom, his grandmother brings in a plate of dinosaur-shaped cookies. Later, just before the Pines twins surrender to the time police, they look in on Soos, and the cookies on the plate are just simple round cookies.
