The Penn Plax SpongeBob Squarepants Pineapple Home is a licensed aquarium ornament modelled on the character's iconic pineapple house. This is the Mini size at roughly 10 x 7.5 x 3cm, making it a good fit for smaller tanks or as an accent piece in a larger themed setup.

It's part of Penn Plax's officially licensed SpongeBob range, so the detailing and colours match the show. The ornament doubles as a hide-out, giving smaller fish somewhere to duck into when they want cover. Aquarium-safe construction means it can stay submerged full-time without affecting water chemistry.

Parents setting up a kid's first tank tend to gravitate to this one — it turns the aquarium into a recognisable scene and gives young fishkeepers a reason to stay engaged with the hobby. The Mini size keeps it in proportion for beginner tanks.
