don't woory. I and alot of other people can help you. A creatu's age will go up by one everyday you have it, starting at zero after you hatch it. When it gets to 15, it will go into its teenage stage. When it reaches 30, it becomes an adult for the rest of its life.
for creatu levals, such as strength and intelligance, you can train them and make them read books to bost them.
if you have any problems, just let me know, ok? You might want to look at the introduction forms to to help you.
