Dandelions can communicate with Beasts and Plants as if it shared a language with them.

When attacked, as a reaction, Dandelions can release the seeds that grow from their heads. This confuses each other creature within 15 feet of the Dandelion and they must make a DC 14 Wisdom saving throw or be incapacitated until the end of their next turn.

This ability can be used a number of times per day equal to the Dandelion's proficiency bonus.

The Dandelion can speak Common and one other language
