Quick answer

Choose Chompy for a lower-cost, simpler build that adds motion to block creations; pick Gorzilla if you want a slightly more involved project with a different mechanical action.

What makes these builds different

Both Chompy and Gorzilla are custom builds from Circuit Cubes by Tenka Inc., designed to bring standard building blocks to life with motion. The main differences come down to price, build complexity, and the type of movement each robot delivers.

Chompy is priced at USD 12.99 (down from a catalog comparison price of USD 19.99), making it the more budget-friendly option. Gorzilla costs USD 13.39 (also marked down from USD 19.99), so the price gap is small but worth noting if you're buying multiple sets.

Build experience and instructions

Both products include build instructions, so you can follow step-by-step guidance. Chompy is tagged as a simpler build, ideal for quick assembly or younger builders. Gorzilla, numbered as build #102, may offer a slightly more engaging challenge without being overly complex.

If you're new to Circuit Cubes, Chompy is a safe starting point. If you've already built a few sets, Gorzilla can add variety to your collection.
