This puzzle is a variant on the well-known connecting wall puzzles. May contain traces of grid deduction and happy stars 😊
Your goal is to fill all the empty squares in the main grid (left) with either path tiles or happy star tiles (right).
Each word/phrase must be connected to a happy star, either directly (orthogonally adjacent) or via one or more path tiles.
Each happy star must be similarly connected to four words/phrases that are thematically related (e.g. names of UK Prime Ministers)
