Five new dragon names for Dragons 2

On April 25 and 26, DreamWorks trademarked several new names in the software, paper goods, clothing, and action figure categories. All of these names were trademarked "in connection with a dragon breed in an animated motion picture." Here is the list:

• Hobblegrunt
• Groundsplitter
• Stormcutter
• Cloudcutter
• Raincutter

If DreamWorks felt the need to trademark these, then they are probably important for the plot (as well as merchandising). So I'm expecting some new dragon toys!
