Can a critter do a normal grapple and then swallow someone, or must it do a "hold" type grapple (at -20) in order to swallow? Below is the text for the critter in question and the general rules for Improved Grab. I've bolded the part that makes me think maybe the critter can only swallow if they do the -20 type of grapple.
Improved Grab (Ex): To use this ability, the creature must hit with its bite attack. If it gets a hold it can attempt to bite or swallow the opponent.
Improved Grab (Ex): ... The creature has the option to conduct the grapple normally, or simply use the part of its body it used in the improved grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on grapple checks, but is not considered grappled itself...
