Release Announcement Pictures
Latest releases were accompanied by a picture with its title, a drawing of the eggs and a funny phrase which is published in the thread of the forum that TJ09 uses to proclaim them to the users. TJ09 posts two to four eggs (which sometimes have a code forming a word related to the release or event) with these images to allow users to follow the stages of growth of the new eggs until they become adults. Here some pictures of the latest releases:
