Flammable. If the tarling takes fire damage, it ignites. It and any creature it is grappling take 2 (1d4) fire damage at the start of each of its turns and its weapon attacks deal an additional 2 (1d4) fire damage on a hit. If the tarling is subject to heavy rainfall or it takes 5 or more cold damage in a single instance, the flames are extinguished.

Oil Form. When the tarling tries to move through water, it instead uses its swimming speed to skim along the water’s surface; it can’t submerge below the surface of water without a powerful detergent.
