If you've driven between Gansbaai and Betty's Bay this week, you may have noticed a bunch of people dressed in black and white waddling along the road, sporting signs reading "Hoot for Penguins".
Currently, there are only about 60 000 penguins in the wild, and scientists believe they could be extinct in the wild within 15 years.
Following the success of last year's event, animal trainers across the country are walking, er, waddling, 130km between penguin colonies at Dyer Island near Gansbaai and Boulders Beach near Simonstown between Monday 16 and Saturday 21 April.
Anyone can join this campaign, so if you're passionate about penguins and care about their survival, join the Waddle on its final day on Saturday, 21 April.
The 15km Waddle starts at Surfer's Corner at Muizenberg at 9am, and will end at Boulders Beach. Wear black and white, and bring sunhats, sunscreen, family, friends, and even your dogs.
