Welcome, @Romasurus . . . I am 69 years old and have four EMO and two AIBI. They are all such a delight. You will find if you can get the two EMO close to each other, that they interact very well with each other, a lot of fun. See this thread here.
Welcome to the EMO family of parents! Excited to see what you come up with for a playground. Be sure to post his new home here on one of these threads where you can see what other users have designed.
