Who would win...?

[Sandshrew4]

Note: This is my first time trying this, so please tell me if I'm doing something wrong.
The rules: The first poster posts a "battle." The next poster says who they think would win, and why. Then they post their own matchup.
Example:
Poster 1: Who would win if a tiger fought an army of termites?
Poster 2: The tiger, because he could just step on the termites. Who would win if a crazed monkey fought a mouse with a bazooka?

And so on.
Additional comments: I got this from my favourite show, Outnumbered.

Lets begin:
Who would win if a Galapagos tortoise fought a baby giraffe?

 

[Wobbu]

Baby giraffe. The tortoise would be too slow.

Air breathing shark with legs or 10 aardvarks?

 

[Sandshrew4]

The shark. All anteaters do is eat ants. The shark would eat the anteaters.
Who would win if a T-Rex fought a fire breathing chinchilla with laser vision?

 

[Captain Gizmo]

chinchilla could use his laser vision to melt the T-Rex before it comes close to him.

A super fast sloth or a very slow sabertooth tiger?

 

[Sandshrew4]

The sloth, cuz it has claws, and the tiger wouldn't be able to do much.
Who would win if a two foot grizzly bear fought a six foot fly?

 

[gimmepie]

The fly because it would spit digestive juices all over the bear and injure it badly before it even had a chance.

Who would win, a sentient sandwich or a robotic pencil?
