Or how about the bubbling mud in LBT 6?
Not only can Ducky, Cera, Dinah, and Dana stand on those bubbles without making them pop, but being enclosed in the bubble apparently enabled Cera to "fly"

The tsunami in LBT 5 was rolling from the coast towards the open sea which is a "rather unusual" thing for any kind of wave to do.
I don't really know if this one fits into this section, but did you realize how inconsistent Ducky and Spike are when it comes to acrophobia? I name just the most significant examples, but there are more throughout the whole series. In LBT 2 and 5 Spike is walking across logs lying across deep chasms with an almost dreamlike sureness (he actually walks with his eyes closed in LBT 5. In LBT 2 he doesn't hesitate to leap across the chasm during the pursuit of the eggeaters. However in LBT 6 he is extremely fearful of leaping across the rocky pillars. In the same movie Ducky has no problem at all to leap across the rocky pillars (she is the one to have the idea and the first one to leap) but she is terrified at the (much less scary) task of walking across the log lying across that ravine later on.
Another thing which may or may not fit into this section are some cases of coloring. I suppose the turning red of everything in case of danger (whether we like it or not) is something that can easily be interpreted as a mere effect that has not too much to do with the real colors. However, why is it that since LBT 8 (and to an extreme extend in LBT 13) we got to see deep green skies again and again? Or green lava in LBT 7? What to make of that? A greet percentage of oxidizing copper in the air and the lava or what?
