When a baby strider is riding on adult back and you feed the baby warped fungus to increase growth the baby grows and turns into an adult but it stays on the others back, you can not separate them now besides killing one of them. It looks very awkward having a stack of adult striders. Also when this occurs the bottom strider seems to not be attracted by warped fungus while the tom one still is but it cannot move because it is still on Tom of the other strider.
