Well, the eating other muppets thing kind of died out after a while, didn't it? Especially since over time, the productions have moved to a set of core characters, there isn't any room for random characters being eaten. But explosions have carried on from their earliest stuff, to the Muppet Show (Crazy Harry blowing Ben Vereen into the ceiling rafters is my favourite example), to the movies (like in MTI when Beaker gets blown sideways into the wall? "Now we know that is definitely too much gun powder!").
