You can only get one pair of boots as of now. No news when the owner will return or a quest. If there was a quest, I think it should be like this: the owner was returning from where he was returning from where ever he was but then got caught by the Lizardons. The cat salmon (or w/e that thing is) notices that he should be back by now and wonders if the Lizardons got hold of him. He then gives you a glove which allows you to pick up heavy rocks (like the titans glove in Loz: Lbw). You then go to the place blocked by a rope and rocks and you can use the glove to pick up all the rocks. This may sound crazy but, in there is a mother Lizardons and some other normal Lizardons. The mother Lizardons eats humans or graalians in this case , to reproduce Lizardons. You're spotted and then you have to defeat the Lizardons that guard the mother. You then defeat the mother and rescue owner. After that he gives you all boots you didn't pick as a reward. The only thing I would say bad about the plan is that is that the Lizardons would stop appearing.
