Alternate Form (Su): As a standard action, a pseudonatural hippogriff can take the form of a grotesque, tentacled mass (though this alien appearance has no effect on the creature's abilities). Other creatures receive a -1 morale penalty on their attack rolls against the creature when it is in this alternate form.

True Strike (Su): Once per day, a pseudonatural hippogriff can gain a +20 insight bonus on a single attack roll. In addition, the creature suffers no miss chance against a target that has concealment or total concealment when making this attack.

Skills: Hippogriffs have a +4 racial bonus on Spot checks.
