At the top of the Illustration Style image, “Happy Birthday Varinia!”

Hand-drawn, fine-line illustration with textured brush strokes and a warm, expressive color palette. A funny underwater birthday scene set in a lush kelp forest that feels like a woodland clearing: towering kelp “trees” sway like a forest canopy, their fronds arching to frame the composition. Center stage, a huge, cheerful whale in a polka-dot party hat glides through, balancing an extravagant, glossy chocolate cake on a mossy driftwood stump. The cake is layered and gooey, topped with tiny mushroom-shaped decorations and bioluminescent bubble-candles. Around the stump, clusters of whimsical sea mushrooms (toadstool-like anemones) sprout from submerged logs; a dapper crab holds a cake server, a pufferfish floats like a balloon, and tiny fish in party hats blow confetti-like bubbles. The whale beams, flicking a fin as its blowhole puffs heart-shaped bubbles. Sunbeams stream down in golden shafts, warming teal and seafoam blues with coral pinks and rich cocoa browns. Balanced composition, playful expressions, visible paper grain, watercolor washes over fine ink linework, and cheeky details throughout for a humorous vibe.

Render the title text in playful, hand-lettered seaweed-green script that gently ripples like kelp.

Include one small caption on a driftwood sign near the mushroom cluster (bottom right): “A kriller, un-fungi-gettable birthday!”
