Happy Plants are the small potted plants in LEGO Botanicals with smiling faces on their pots. 10371 Cosy Plants from November 2026 builds a peppermint plant and a chamomile plant. The brown pot is reading a book and the purple pot holds a cup of tea, and the two plants swap between pots. The idea started with 10349 Happy Plants in 2025, a baby dracaena and a baby pilea, which is listed under the Botanical Collection.
