"Who the frack am IIIIIIII asks giant? I am - HUNGRY!" Jeffy replies in Giant.
Lots of things Johan's thrown his way so far have been outside his comfort zone but Jeffy is quite used to people trying to skewer him, this is basic stuff! His ogre legs extend like springs for a brief second and he goes rolling and tumbling perpendicular to the charging pair, ending 15 feet away - just out of reach of the mammoth's tusks but close enough to set up an attack of his own!
"And you're clumsy! And will be... delicious!"
He lurches forward and pulls off a short spinning leap at the end to strike Johan rather than his crispy mount.
Edit: 25 to hit, 41 damage Vital Strike as standard action. (no swift action for Up Close and Personal as originally planned)
