Troglofrog
From Enormous Bullfrog. The sound of the troglofrog echoing throughout deep caverns sounds almost like... ragtime music? Aquatic type. This cute little guy only has 83 HP! Be advised that you will need a lower level pet (or one with superbark) if you wish to catch him.
Troglofrog is a battle pet available from wild encounters in Khaz Algar or from NPC vendors.
Guide awaiting review
Catch Troglofrog in the wild
Find Troglofrog at Isle of Dorn or in The Ringing Deeps at 54.0, 32.6. Use a lower-level pet or one with Superbark to weaken it before capturing, as this pet has only 83 HP at higher qualities. Terrible Turnip is recommended as a capture team leader since its Weakening Blow cannot reduce the opponent's health below 1 HP.
Purchase from vendor alternative
Alternatively, purchase Troglofrog from Enormous Bullfrog in Razorfen Kraul or from Flik at Darkmoon Island at 52.4, 62.2.
Tips
Troglofrog can spawn as a secondary pet in battles; if you have trouble finding it, kill critter versions to spawn the battle pet version.
