Trivia

 * In flashbacks, Krokorok watched Ash participate in the finals against Iris in the Don Battle Tournament in BW044: The Club Battle Finale: A Heroes Outcome!, tried to get on the train in BW053, saw Ash enter the Driftveil Gym in BW063 and was the one who thew the pen that belonged to Prof. Cedric Juniper that startled the Klingklang in BW065.
 * Poison Tail returns to the series.
 * Who's that Pokémon?: Krokorok (Japan) Scolipede (U.S.)
 * Ash and co. may have encountered several Scolipedes that are wild in the wilderness in Unova before since BW009: The Bloom Is on Axew!, and some Palpitoads before since BW034: Ash and Trip's Third Battle!. And some of the Scolipedes and Palpitoads belonged to many trainers in Unova including Ash's Palpitoad and Clay's Palpitoad excluding Seismitoad, the evolved form of Palpitoad.
 * This is the second time Ash looked up Scolipede on the Pokedex since BW009: The Bloom Is on Axew! but the difference is, it said "the evolved form of Whirlipede" which the Castelia City Gym leader Burgh has one in BW025: Battling For The Love of Bug-Types! which it battled Ash's Sewaddle now evolved into Swadloon and lost.
 * This is the only time in the episode when Ash looked up each Pokemons on the Pokedex one by one when another image picture of another pokemon appears.
 * This is the third time Ash's Pikachu used Thunderbolt on a Unova Ground type Pokemon that wouldn't work. First was the Sunglasses Sandile in BW020: Dancing With the Ducklett Trio! since it evolved into Krokorok in the end and got blown away. Second was Iris' Excadrill in BW044: The Club Battle Finale: A Heroes Outcome! during the finals in the battle tournament in Nimbasa Town. This time he used it on the Sunglasses Krokorok.
 * This is the second time Ash mentioned about Krokorok's type is. The first was BW063: Battling the King of the Mines! but the difference is, Ash told Pikachu that its a Ground-type, and now he said to Nick that its a Ground/Dark-type.
 * This is the 2nd time Ash caught a pokemon that wears a sunglasses. First was the leader of the Squirtle Squad named Squirtle in IL012 Here Comes the Squirtle Squad. The difference is, there were no other Krokoroks like this one to follow that Ash's Pikachu encountered with.
 * Its true that Iris said that Krokorok's not one of Ash's Pokemon and happens to be a #1 rival for Pikachu but when Ash told him to come along with the group when he felt sad after he lost to Pikachu in the end, he's now one of Ash's as a new friend and catches him in his Poke Ball.
