Build the SD EX-Standard Hello Kitty and RX-78-2 Gundam set without frustration. Follow these snap-fit steps, avoid common mistakes, and display the hybrid form.

Quick answer

Build the RX-78-2 Gundam and Hello Kitty separately first, then combine them into the hybrid form. Snap-fit assembly means no glue or paint is required, but cleaning nubs and test-fitting parts will keep the set looking sharp.

Why this set is a good first SD build

SD EX-Standard kits are designed for quick, push-fit assembly, and this two-pack adds a second figure and a display stand. That makes it a low-risk way to try SD proportions before moving to a larger grade.

The Hello Kitty figure can sit and hold her apple on the included apple-shaped stand, so you get two finished displays from one box. The trade-off is that small parts and color separation are simpler than on a high-grade kit, so don't expect the same detail.

What to check before you start

Open the box and confirm both runners and the stand are present. The set includes the SD RX-78-2 Gundam, an equally-sized Hello Kitty, her apple, and the apple-shaped figure stand.

Work at a clean, well-lit table and keep small parts in a tray. The Hello Kitty figure and apple are easy to lose, and the hybrid combination means you will handle parts more than once.

Step-by-step build and display sequence

Sort and snip parts: Cut parts from the runners with hobby nippers, leaving a small nub. Common mistake: twisting parts off by hand, which can stress or crack the plastic. Keep the runner label visible until each part is placed.
Clean nubs before assembly: Trim remaining nubs flush with a hobby knife or sanding stick. Check the fit before pushing parts together; if a peg resists, re-check orientation rather than forcing it. A dry test-fit now prevents a loose joint later.
Build the RX-78-2 Gundam first: Assemble the SD Gundam from the feet up, then attach the torso, head, and arms. Keep the joints slightly loose until you see how the hybrid combination will attach. Leave the head and backpack off until you test the hybrid fit.
Assemble Hello Kitty and her apple: Build Hello Kitty, then place the apple in her hands. Check that she sits securely on the apple-shaped stand before moving on. Test the sitting pose on the stand before combining figures.
Combine into the hybrid form: Follow the set's combination layout to join the two figures. Common mistake: forcing a connection that is not aligned; re-check the peg and socket direction first. If a connection feels tight, stop and inspect the alignment.
Choose a display setup: Display the Gundam and Hello Kitty separately on the stand, or keep the hybrid form together. Avoid direct sunlight and heat, which can warp snap-fit joints over time. Decide on one pose before tightening any loose joints.
