The event was a huge success, with the children enjoying face painting, balloon artists, games and prizes, and a chance to swap trading cards with their friends.
Ellenbrook was one of just two WA stores to host a trading day.
The wildly popular Aussie Animals series of 108 trading cards features animals, including endangered leatherback turtles, saltwater crocodiles and cuddly koalas, from nine different Australian habitats. Each card has a fun fact about the animal.
The trading cards are given away with purchases from Woolworths stores.
