Fan Casting Emperor Sea Strider in Expedition

[Sanders] - Is..walking?! The Emperor Sea Strider is the largest living thing in this world (35 meters), which invokes a low rumble, which echoes like thunder. They live in the so-called Amebian Sea (actually a vast gelatinous organism), which they consume as food through their feet, but they need to be constantly walking, as the gelatinous surface of the "sea" cannot otherwise support their massive weight of 190 tons with another way. They are peaceful, with their young flying around them like insects. Sanders and Ike end up unknowingly going up together with Darwin in one of them, which ends up becoming a way for them to cross the "sea" in the middle of a storm.
