Tangela is covered with thick blue vines that obscure its face so only its eyes can be seen. The vines give it a round shape, although it is unknown what it looks like without them. The vines are covered in fine hair. It has a pair of red boot-like feet, but no visible arms.
Tangela's vines never stop growing and are easily replaced if lost or damaged. Tangela can ensnare and entangle its foes with its vines.
Its thick blue vines are constantly jiggling and swaying. This appears to be a defensive technique, as the movement unnerves enemies and deters herbivores that might mistake Tangela for a shrub. Any moving object that gets too close to a Tangela will be ensnared by its vines. This also appears to be a defensive technique, because Tangela's vines will snap off easily and painlessly if the target pulls on them, suggesting that the ensnaring is intended to scare off potential predators.
Tangela can usually be found on the edge of many grassy plains, be it near a mountain range or the ocean. However, they can also be found in large forests or the jungle on some occasions. They are most common in Kanto and Johto.
