The front door of Grandma's house is yellow during the day as Little Critter and Grandma wait for the bus to pick them up to take them to the beach. When they come home later at night, the front door is purple instead of a darker shade of yellow.
Little Critter loses his visor on Page 2 after he attempts to set up the beach umbrella - only for the wind to blow him in the air where he lands with the umbrella upside down while he's underneath its canopy. On Page 5, it is back on his head without an explanation how he retrieved it. After that, he doesn't wear it again until on Page 11 when he and Grandma take the bus to return home.
On Page 7, a motorboat driver and its passenger going water-skiing are near the beach and between some beachgoers that are in the water. It is illegal to drive a motorboat within 100 feet of range from a beach, as the beach depicted in this game has no barriers as safeguarding from oncoming motorboats.
