Those two would be a waste to include as exhibit animal only if the exhibit animal are still unmoving and unresponsive as they currently are. If we have the frilled lizard, we at least need an animation with it deploying the frill, and any basilisk would need the ability to run on water. I guess the frilled lizard could be put into a walkthrough exhibit (though it would be a bit weird imo), but I think the basilisk should be put in habitats.
I mean all the exhibit animals move to some extent, ofcourse some more than others.
The tortoise for example has a couple animations where they walk around, so giving the frilled dragon an animation where they frill up should be more than doable.
And having an animation where a basilisk runs from a to b and then back doesnt feel impossible either to be honest.
The gripe i have with this is that both of these, and also the hooding up of cobras, are responses to being threatend, so you really should avoid seeing these.
Which is also why putting the frilled dragon into the WE so they can play their frill animation is genuinely a horrible idea. Having the guests constantly scare the lizards so much they have to frill up is pretty much animal cruelty, no animal in a zoo should be under constant fear for their life.
