((from Wikipedia) The tooltip or infotip or a hint is a common graphical user interface element. It is used in conjunction with a cursor, usually a pointer. The user hovers the pointer over an item, without clicking it, and a tooltip may appear—a small "hover box" with information about the item being hovered over.)
Many Wikia wikis use tooltips for their content, whether it be the default tooltip or a custom tooltip. Now, since I'm not all that experienced with templates, I decided to give a tip on how to use the default tooltip. This is how it is done:
<span title="Character that calls them that name">Alias goes here</span>.
So, if we were to apply this (for example) to the Yellow Tattletail,
<span title="Mama Tattletail">Butternut*</span>
Butternut* (hover mouse over it to see). (I use the asterisk to mark that a tooltip is there, as a visual clue. It's not necessary, but it helps.)
