Wonderful PvP scouting mount! They don't poop, so stamina fills quickly, less fall damage, quick getaway, stealthy swimmer/close to ground, if someone comes at you with a flyer you can escape via water, jumping the full forward distance begins stamina recovery, stamina isn't used while swimming, can be used to tame lower level dinos as it's attacks add torpor, cementing paste and chitin are easily obtained and not to mention that the frogs look great! The "stabbing" tongue attack gathers more efficiently but does less damage than the "slashing" tongue attack. Note that you can NOT attack via the tongue while swimming. When using to tame, be sure to wait 5-10 seconds between attacks, the wild dino will likely die otherwise, not very efficient but very handy.
