"Bouncy Box" ist der Abschlussbildschirm eines Kindervideos im hellen Cartoonstil. Hüpfende Regenbogen-3D-Buchstaben und ein Bogen "Watch more" stehen links unter einem kleinen Regenbogen in flauschigen Wolken, darunter ein weißer Abo-Ring, rechts zwei abgerundete weiß gerahmte Videofelder auf Himmelblau. Tausch den Namen und leg die YouTube-Elemente darauf.

Create a finished 16:9 YouTube end-screen background for the kids’ channel. Bright sky-blue field with soft white cloud clusters kept to the outer edges, leaving the center clear. Use only these exact words, with no additional text: headline “Bouncy Box”; supporting line “Watch more”. Set “Bouncy Box” large in the left half, stacked on two lines, in chunky rounded custom lettering with inflated, softly beveled faces; each letter is a different saturated rainbow color, with crisp highlights and a thin clean white keyline for strong small-scale readability. Place “Watch more” above it in smaller rounded white lettering, with a short curved rainbow accent beneath. Add a restrained rainbow arch and a few small rounded cloud puffs around the wordmark, without crossing the text or the empty end-screen areas. On the right half, create two large, completely empty, identical horizontal video areas, one above the other, each a clean rounded rectangle with a thick white frame and a subtle pale-blue inner stroke. Leave their interiors plain sky blue: no thumbnails, imagery, lettering, play symbols, gradients, or interface graphics. Add one large empty circular subscribe area below the wordmark, with a thick white ring and plain sky-blue center; do not put a button icon or text inside it. Keep all important text and frames within generous safe margins. Leave clear breathing room between all elements; nothing overlaps. Flat, polished children’s channel graphics with a few smooth dimensional highlights, vivid rainbow colors, soft cloud shapes, crisp edges, even bright lighting, and uncluttered negative space. The overall reading order is “Bouncy Box”, “Watch more”, then the two empty video frames and empty circle. Render the copy exactly as quoted and nowhere else.
