Ways to add natural attacks to a party member?

[Tvtyrant]

I'm playing a Wizard right now and I Planar Bound a Celestial Baleen Whale to use as a mount (I gave it my winged mask) and I want to add some natural attacks. The thing is really strong, so it should hit hard but alas right now it only has one attack.

What are some ways to give it temporary natural attacks? As many as possible please.

Edit: Girralon's blessing.
Shape Soulmeld
Claws of the Savage
Yochlol Blessing

Girallon's Blessing (SC) the creature touched grows a pair of gorilla arms, with claw attacks. (Its other arms also grow claws, if it has arms).

They're not Wizard spells, but the Bite of the WereX line can be used, with the appropriate spellblade, to give someone else natural attacks.
Generally, spellblades can be used to cast personal buffs on someone else.

There are a number of items you could use as well, like the fanged ring, the horned helmet, or the monk's belt.
