These were promotional videos for the annual release of the Reverse Retro jerseys. Reverse Retro is something that every NHL team takes part in and is created by Adidas. They get jerseys and a collection of other merch that are inspired by retro designs. On top of that some teams, like the Islanders were re-releasing an old mascot, Nyisles. So the first video is for the announcement of Nyisles. And the second video is for the release of the Reverse Retro jersey.
