Design a whimsical Father's Day themed cartoon without a human figure. The main feature is a joyful charcoal labrador wearing a captain's hat, firmly holding a fishing rod in its mouth. The line from the rod is plunged into the water where it captures a cartoon shark looking surprised yet untroubled. In the background, a picnic blanket is laid out containing a hot cup of tea and a note that reads 'To the World's Best Dad!', surrounded by diverse Father's Day greeting cards.

Generated with these themes: Charcoal labrador, Shark fishing, and A nice cup of tea.
