Marshall wears other pups' pup packs and hat for the first time.
This is the first (Marshall with Rubble's), second (Marshall with Chase's) , third (Marshall with Zuma's), and forth (Marshall with Skye's), time a pup has worn another pups' pup packs.
This is the third (Marshall with Rubble's), fourth (Marshall with Chase's), fifth (Marshall with Zuma's), and sixth (Marshall with Skye's), time a pup has worn another pups' hat. The first time was when Chase wore Rubble's hat in "Pup Pup Boogie", and the second time is when Zuma wore Rubble's hat in "Pups Save a Super Pup".
Katie rides with Marshall in his truck for the first time.
This is the second time Ryder was not the one to give orders to the pups for a mission (with the orders given by Marshall). The first time was in "Pups Save Ryder" (with the orders given by Chase)
Marshall's apparent fear of bouncing on the trampoline is discontinuous with "Pups Save the Circus", where he is seen having fun while bouncing high on a mattress with Rubble and Skye, and "Pups Save a Flying Frog", where he is bouncing on a trampoline while attempting to teach his pet frog, Smiley to jump very far.
In one scene, Rubble describes dreaming of cats being able to talk. This is another instance of "breaking the fourth wall" since dogs do not speak in real life.
When the pups are seen driving off to parachute practice, they are in uniform with their pup-packs, but when Marshall goes on the mission by himself, he brings all the pups' outfits and pup-packs with him.
