It's a short story on an anon's attempts to catch wild yukkuri with improvised pitfall traps in the form of empty cup noodle containers lightly buried in the ground.
The shocked expressions in the illustration are because the yukkuri parents were caught in the holes. Since the holes are wide enough to hold them in place while keeping their "feet" suspended, they can't move, and they're too stupid to free themselves.
The anko ends with the anon contemplating on whether to abuse them or not.
