A Hydra residing in Froggy Bottom Bogg chases the main characters in Feeling Pinkie Keen. The hydra has four heads on snake-like necks and a large, orange, dragon-like body, with only two legs and no wings or arms. The ponies note a smelly gas that envelops it as it rises from the bog, and a tick-like insect can be seen on its neck during this scene. Before chasing the ponies, it roars and licks its lips. The heads sometimes display different expressions and even laugh at each other's misfortunes. One head is noticeably slower to react than the others.
