blue group · The short answer
___HEAD
Each puzzle word passes the same exact test. The four mappings show how the answer works.
BOBBLE plus HEAD forms BOBBLEHEAD, a figure with an oversized head designed to nod or move.
HAMMER plus HEAD forms HAMMERHEAD, used for a hammer's striking part and for the distinctive shark.
JUG plus HEAD forms JUGHEAD, the familiar combined name associated with the Archie Comics character.
SLEEPY plus HEAD forms SLEEPYHEAD, an informal term for someone who is sleepy or slow to wake.
Why this group was difficult
- The completed forms belong to unrelated subjects
The results range across a nodding figure, a tool or shark, a character name and an informal label for a tired person. - JUGHEAD depends on recognizing a proper name
Unlike the more transparent BOBBLEHEAD and SLEEPYHEAD, JUGHEAD is most readily recognized as a character's combined name. - BOBBLE is caught in the board's spelling trap
Its visible resemblance to COBBLE, GOBBLE and WOBBLE can delay testing it as the first half of a compound.
How to spot this pattern next time
When unrelated words remain, test a shared prefix or suffix systematically. Write the same candidate beside all four and require recognizable results every time.
A completed-word category may mix common nouns, nicknames and proper names. Judge the construction itself rather than expecting the results to share a subject.
Four useful facts behind the group

- A hammerhead is the striking end of a hammer as well as a kind of shark.
