Chuck thought about it, then remembered there were some caves nearby.  He ran out into the direction of the nearest cave, sending out Nessie to ride on as they reached the river leading into the cave.  As they travelled down the river, he kept an eye out for any mushrooms, hoping he'd find the right ones.  It was then that he noticed one giant mushroom, that seemed to be glowing with a similar energy to that of Dynamax energy and the wishing stars.  He hopped off of Nessie and carefully harvested it, hopping back on her and travelling back down the river to the Dojo.
