There are a number of aircraft listed as "Tundra Tundra" but are quite different. Some are Dream Aircraft Tundra's which look somewhat like Cessna 180's with two wing struts, the others look like Joplin Tundras or Laron Tundras.
One, C-FULB, has dreamaircraft.com painted clearly on the engine cowl. Many do not have photos, so I cannot identify them.
