Hi there, While editing, please do not create stub articles with little text or minor subjects without sizable information. Also, please do not also copy content from the DuckTales Wiki; such activity is considered plagiarism and unproductive.
In future when you write episode pages please remember to include the following when its available. Do not just write up a small introduction along with an infobox and some categories, then move onto the next one. You need to put more work into it.
Because there is no article on Black Heron, and the one you just made lacks contents. Don't just create a new article with hardly anything just so you can put up links. A small introduction, an infobox filled with notes, a navbox and some categories isn't enough. Readers want to know about this character. Who she is and what was her role in the show. Don't recreate Black Heron's article unless you plan to put some work into it.
