Shroob Mushroom

This uninteractable overworld object is created by a special overworld attack by a member of the Shroob race (usually a boss or iconic character), transforming the affected character into a purple mushroom. There is, however, one case in which no attacks are involved in the process. Some notable characters that get transformed are Toadbert, Kylie Koopa, and Bowser Jr. These, as well as all other Shroobified objects, can be reverted back to their original form when touched with abby tears, as demonstrated by Baby Luigi after the final boss battle.
