Slimefoot

Slimefoot is a Thallid which grew out of a small spore attached on the hull of the reconstructed skyship Weatherlight on Dominaria. As such it became an unofficial member of Captain Jhoira's crew.

History
The hull of the skyship Weatherlight was formed from a Weatherseed that Maro-Sorcerer Molimo (the avatar of the Llanowar forest) gave to Jhoira, and thus it contains part of the soul of the forest. In Jhoira's restoration of the skyship, some spark of life took root in the wood and eventually grew into Slimefoot.

This thallid is something like a mascot and a deck swab, tending a herd of saprolings that help keep the ship clean. Slimefoot is apparently harmless, somewhat adorable, and evidently useful, so Jhoira and the rest of the crew tolerate the thallid's presence. Passengers are warned to keep out of Slimefoot's way, but the grumpy fungoid is easily plied with food.

At the time of the Weatherlight attack on Belzenlok's Stronghold Slimefoot played a pivotal role by procuring the help of Muldrotha, Urborg's elemental avatar, and steering the skyship during the attack by Yargle.
