The video says it best...
I did this in Fantasy Hyrule, a 1.90 quest.
EDIT: More info! Not all tektites do it for some reason. On the screen in question (1:6C), there's three tektites that all do it, but two screens east of there (1:6E), there's two that don't... The only difference I can see between the two screens, enemy wise, is that 6C has Zoras, and is set to "Enter from sides (Consecutive)", while 6E is set to "Spawn (Classic)"...
