Deku Toad

The Deku Toad is the mini-boss of the Lakebed Temple in Twilight Princess. The Deku Toad is initially clinging to the ceiling, and begins the fight by dropping down to the floor and shaking off several Toado eggs from it back. Like most small swarming enemies in Twilight Princess, the hatchling Toados can be dealt with efficiently using the Spin Attack.

Strategy
The Deku Toad's attack pattern is to jump to the ceiling, attempt to fall down on Link, and shake off more Toado eggs. If Link can roll out of the way in time to avoid being crushed, it can be stunned momentarily, allowing Link to strike its exposed tongue. Following this, if Link can manage to shoot a bomb arrow into its mouth, it remains stunned again, exposing its tongue once more. Otherwise it continues its attack pattern. After several hits to its tongue, the Deku Toad remains destroyed, but not before coughing up a chest containing the Clawshot.

The Deku Toad is a giant version of the Toadpoli enemies, which bear much similarity to Octoroks from previous games. The Toado could therefore be the tadpole stage of the Toadpoli.

The Deku Toad is similar to the "real-world" Surinam Toad as they both carry their eggs on their back.

Trivia

 * The Deku Toad bears some similarity in the way it acts to Wart, a mini-boss in the Great Bay Temple. Like Wart, it has many eye-like objects on its body (though these are actually its eggs), but not nearly as many as Wart did. It also starts the battle on the ceiling, like Wart. Interestingly enough, the final boss of Super Mario Bros. 2 is a giant toad named Wart.
 * Like Molgera from The Wind Waker, its weak spot is its tongue.
 * Midna is repulsed by the Deku Toad and, as such, does not wish to take part in the battle.
 * Despite its name, the Deku Toad looks more like a frog rather than a toad, due to its lack of warts.
 * The Deku Toad, along with Ook, are the only mini-bosses in Twilight Princess to have their own battle music. All other mini-bosses share the same battle music (with the exception of Death Sword and Phantom Zant, who share a unique battle music).
 * It is unknown why it has the prefix "Deku" in its name, considering that the Deku are a plant-like race in the Zelda series.
 * It is unknown how the Treasure Chest containing the Clawshot could be inside the Deku Toad. It is likely that it found the chest within the dungeon, and, mistaking it for food, ate it.
