Does a Zefaheen animal companion need a trick to use its air walk ability?

[deuxhero]

Genie-Touched Companion gives you an animal companion that functions as a horse (so still intelligence 2 and animal type) but gains the special abilities of the genie-touched horse type you pick. For Zefaheen this gives air walk as an SLA to the horse itself. Problem is, per Air Walk's description, an animal companion needs a trick to use air walk.

Does a Zefaheen really need to blow a trick to learn how to use its own ability?

[Chell Raighn]

The rules for Air Walk specifically call out using Air Walk for a mount. The Zefaheen animal companion should be able to utilize it's Air Walk SLA on itself just fine so long as you are not using it as a mount. The trick would be required to utilize your Zefaheen companion as a mount while it Air Walks though.
