King Boo Coloring Pages

King Boo Coloring Pages: 17 printable PDF designs featuring realistic character portraits, action and expression variations, and a spookier villain-style look. Each page can be downloaded as a PDF to print or colored online in the browser.

King Boo debuted in 2001 as the final boss of Luigi’s Mansion on the Nintendo GameCube, where he traps Mario inside a painting and sends Luigi to rescue him. As the ruler of all Boos, the shy, round ghost enemies that first appeared in Super Mario Bros. 3, King Boo shares their signature trait: Boos freeze and hide their faces the moment you look directly at them, only moving or attacking the instant your back is turned. King Boo has two very different official looks. In the Luigi’s Mansion games, he has a greenish tint, glowing red eyes, fangs, and a gold crown with a ruby, giving him a more sinister design. In spin-off games like Mario Kart, he appears in a friendlier white body with black eyes and a gold, jewel-topped crown.

This collection groups its 17 pages by style, from true-to-life character portraits to action and expression variations and a spookier villain look, so kids and fans can pick a page that matches their skill level. Each page is available as a downloadable PDF or as an online coloring tool that works directly in the browser.

What Is Inside This Collection

The 17 pages are split into four groups based on style and content.

Realistic King Boo Portraits

The largest group shows King Boo in his standard spin-off game appearance. Use White for the rounded body, Black for the simple eyes, and Gold for the crown, adding a small Blue or Red gem at the center.

King Boo in Action and Expressions

Three pages show King Boo driving, laughing, or scowling. Keep his body colors consistent with the realistic group, and exaggerate the eyes and mouth shape to match each page’s mood, wide and bright for a funny expression, narrowed and sharp for an angry one.

Spooky and Villain King Boo

Two pages lean into King Boo’s more sinister Luigi’s Mansion look. Use a pale Green tint for the body instead of white, add glowing Red eyes, a Blue tongue, and small white fangs, and keep the crown Gold with a Red ruby at the center.

Simple Beginner Sheet

One page uses a large, bold King Boo outline with very few small details, making it a good starting point for toddlers and preschoolers. A single flat White fill with a simple Gold crown is enough to complete this design well.

What King Boo Coloring Pages Do

Fine motor development. King Boo’s crown is made of several small, pointed sections topped with a colored gem, and keeping those points crisp and evenly spaced takes closer hand control than a plain round shape. The American Academy of Pediatrics identifies fine motor skill development as a core benefit of structured coloring for children ages 2 through 7, and the crown’s jagged detail gives that practice a genuinely precise small-shape challenge.

A shy species with a clever rule. Ordinary Boos, the ghosts King Boo rules over, are famously shy and freeze in place the moment you look at them directly, only moving when your back is turned. That gives parents and teachers a natural opening to talk about how a video game can turn something spooky into a genuinely clever game mechanic instead of something purely scary.

Anxiety reduction through focus. A 2005 study in the Art Therapy Journal documented measurable reductions in anxiety following structured coloring sessions. The repeated round, floating shape across King Boo’s different poses offers a steady, low-pressure form to color, which suits that kind of unhurried session well.

Two looks, one character. Because King Boo has two very different official designs, a friendlier white version and a more sinister green one, colorists get a rare chance to practice using color alone to shift the mood of the same character shape.

How to Color King Boo Pages Well

• Body, friendly version: Use Crayola White as the base, keeping the surface smooth and rounded.
• Body, spooky version: Use a pale Green tint instead of white for a look closer to King Boo’s Luigi’s Mansion appearance.
• Eyes: Use simple Black eyes for the friendlier look, or glowing Red eyes for the spookier villain version.
• Crown: Color the crown Gold, adding a Blue or Red gem at the center, depending on which official version you’re following.
• Spooky details: For the villain-style pages, add a Blue tongue and small White fangs peeking out from the mouth.
• Simple beginner sheet: A single flat White body with a plain Gold crown, applied without extra shading, is enough to complete this design well.
