- Are you wanting your school pet Mammoth? (You're not a high enough level to get him yet)
- Are you wanting to hatch with someone to get a Mammoth?
- Are you wanting one just for looks (an original gen Ice Mammoth has bad talents), or one with better talents?
If you want help with something, please be sure to provide as much information in your post as possible. Your one-line sentence is leaving me hanging as to what you really want.
