Pedalos are small boats that resemble ducks. They are used for aquatic transport, both in the Alma Meat Fountains and in the Bismark Park. It is unknown how they are controlled, be it by pedals as the name would suggest or if they are sentient creatures. However, their direction is able to be influenced by motors, as seen in the carnival portion of Zone 2.
Pedalos are accessed mainly in the meat fountains of Alma and the carnival in Zone 2 by using access points which are blocked by Elsen. Upon confronting the Elsen blocking the access points they will turn into Burnt which you have to fight in order to spawn a Pedalo in the designated area. It also seems that only one Pedalo can exist at a time, meaning that there may only be one Pedalo that transports itself.
