Sometimes as drops or purchased from the Black Lion Trading Company, there is a box that you can bring out and players basically can have fun! You open the box and never know what goofs or gags you will get. The box is available for 15 minutes. Players can keep opening the box until it disappears. The transformations last for roughly 15 seconds. Here are some screenshots of what happened with Adaliind when she opened the box. (Some of the screenshots not shown were the fireworks, the dance moves, other animal transformations and the petrified look ).

Transformed into a Skritt
And lastly, a giant form of myself
