Wisdom of the Gnomes (Spanish: La llamada de los gnomos, literally "Call of the Gnomes") is the first spin-off of The World of David the Gnome. It was produced by BRB Internacional and Televisión Española. It follows Klaus, a judge who travels with his assistant Danny on Henry the Swan and aims to solve disputes and lawsuits between animals peacefully and wisely. Like in The World of David the Gnome, trolls also appear. David and Lisa also appear in the final episode, though in the English dub, Tom Bosley and Jane Woods did not reprise their roles. The penultimate episode features Wil Huygen and his wife, the only pair of humans in direct communication with Gnomes. Klaus and Danny complain to Huygen of "inaccuracies" in his book, though what these errors are is not made specific.
