“Giving us a new mold of Guinea Pigs in a small set, LEGO Friends is certainly generous for 2025. The Guinea Pig Playground set gives us two coats of Guinea Pigs, as well as a fun little course for them to run around on. Another small less than $20 set that gives people... More access to new molded animals for the 2025 rollout is fantastic for LEGO. Even though the set is somewhat simplistic, the allowing people to budget and get the new exciting things is a great move. Highly recommend.”

BrickEconomy Member Review
“Guinea Pig Playground includes two new guinea pig molds—Ruby and Lucky—alongside a compact play area featuring slides, a spinning platform, a water bottle setup, and accessories like a yarn ball and plant details. At $10 for 86 pieces, the set offers solid value, especially for collectors interested in LEGO's expanding animal molds.”
