With the 30th Anniversary of Super Mario coming up, there's lots of celebration of the iconic franchise. We're running daily articles on Mario Memories and Mario History here on Nintendo Life, and plenty of websites and YouTube channels are also looking at the iconic mascot's games.

Did You Know Gaming? has done its fair share of Mario videos in the past, and its latest certainly has some neat snippets of information. It takes a look at Dr. Mario and its early prototypes, and also checks out Power-Ups that were considered for the platformers; we're rather sad that Chicken Mario, in particular, never saw the light of day.

Check it out below and let us know what you think.
