As Soto slowly makes his way toward Roshan, Manny knocks him aside to a rock wall, the impact causing sharp icicles to fall on the evil saber, impaling him and instantly killing him.
Then scaring off the other cowardly sabers.
"Sorry fellas! He caught a little frostbite!"
Sid defeating the dodos single-handedly.
Sid's ice-skating (well, until he crashes) and later his skiing and snowboarding away from the sabers.
Manny taking on two rhinos to protect Sid. To reiterate, he doesn't like Sid, he just seems like an annoyance and while the rhinos seem to have a real grudge against him, when they say they're just gonna kill him and leave the corpse for the vultures, what's Manny's reaction?
Hell, even just watching Roshan's tribe fighting a pack of Smilodon with nothing but stone weapons and a pair of dogs. It was pretty clear by the time the dogs were released that if Soto hadn't pulled them back, Runar and his tribe would probably have had a few more Saber pelts to wear.
