LEGO Pumpkin MOC: Step-by-Step Halloween Build Guide

Here is the short version first: a pumpkin MOC of roughly 450 parts takes about 2 hours to build and finishes at about 14 cm tall and 16 cm in diameter. Curved orange slopes give the shell its roundness, and a light brick tucked inside makes it glow. It is the most photogenic desk piece you can put out for Halloween.

Step 1: The Pumpkin Body

The body is the core of the build and accounts for about 300 parts. Start at the bottom and work upward in layers, pulling each ring inward with orange curved slopes. Build the eight vertical ribs first, then fill the gaps between them with curved slope pieces — the rounded look appears almost immediately. Leave an opening of roughly 6x6 at the base so you can push a light brick inside later or use the space for small storage. The top narrows gradually to leave room for the stem.

Step 2: Stem and Vine

The stem is stacked from brown plates and cylindrical pieces, about 50 parts in total. Add a short length of green hose at the top and bend it into a curl to read as a vine — it lifts the realism considerably. A few green leaves scattered over the shell help too: build the veins from plates and attach them at slightly irregular angles on the sides so the pumpkin does not look flat. Finish by adding four small foot pads underneath so it sits steady on a shelf.

Step 3: Face and Lighting

A Halloween pumpkin needs a face, and that is about 100 parts. Build triangular eyes and a jagged mouth from black plates and attach them to the front. If you want to play with it, make the face a removable panel and swap between two designs — a smile and a grimace. Hide a warm-toned light brick inside and the glow leaks out through the gaps around the eyes and mouth, which looks its best after dark.

Parts and Display Ideas

• Main colours: about 300 orange parts, 50 brown, 50 black, 30 green.
• Budget: roughly 70 to 120 yuan for the 450 parts. Buy the orange curved slopes separately, sorted by colour.
• Scene building: pair it with bats, ghosts, a small witch and a fence base to make a Halloween micro-scene.

FAQ

Q: How many parts does a brick pumpkin MOC need? A: The basic version runs about 450 parts, with around 300 of them in the orange body, and costs 70 to 120 yuan. If you only want a mini version, about 200 parts is enough and it comes in under 50 yuan — a good way for beginners to test the water.

Q: Can a brick pumpkin actually light up? A: Yes. The opening left in the base takes a warm light brick or an LED, and the light escapes through the gaps in the eyes and mouth. It gives you the full Halloween mood and is safer and more durable than a real carved pumpkin.

Q: How long does it take to build one? A: About 2 hours for a beginner, and under an hour for an experienced builder. The tricky part is keeping the ribs on the curved slopes aligned. Get the first layer right and each ring above it narrows smoothly. Overall difficulty is medium-low.

Q: How is a brick pumpkin different from a real jack-o'-lantern? A: A brick pumpkin does not rot and needs no carving. Pull the light brick out and it works as a storage box or ornament again and again, and the face panel can be changed whenever you like. A real pumpkin is more of a ritual, but it only lasts about a week.

Q: Where can I download pumpkin MOC instructions? A: Search the "pumpkin" or "Halloween" tags on the BrickPlan platform. There are original instructions in several sizes and face designs, each with step-by-step diagrams and a parts list, so you can follow along and build a pumpkin that lights up.
