[@Sombrero] Those Siren plants are metal. Sheets accepted. I have a question about the giant frogs though. How far can they jump? The distance is going to decrease as mass increases unless their planet is lower gravity.

Much like human jumping distance, it varies greatly depending on how often they jump around in their day-to-day lives. The general rule of thumb is that they can jump three times their sitting height straight up, and 3.5 times that in a horizontal direction, although horizontal arcs will very because I am not a good trajectorist. Athletes may go higher, lazy ones (If they can find a way to survive in Tchernabog, which is a feat in itself) may go lower, but it's safe to make the general assumption. It's like being able to judge that a big guy can lift more than a smaller guy at first glance, except usually more accurate. Tree frogs, because they jump up and down trees, tend to be frequent rulebreakers, but their muscles are still proportionate to their bodies and, pound for pound, no stronger or weaker than any of their fellows, so expecting a tree frog to jump further is like expecting a water frog to swim better, they probably would.
