Giant frogs are not off-guard when <a href="/action/balance">Balancing</a> on a narrow surface, and they gain a +4 bonus to Reflex saves to avoid falling.

Sticky Feet

A creature hit by the riding frog&#x27;s tongue becomes <a href="/condition/grabbed">Grabbed</a> by the riding frog. The creature isn&#x27;t <a href="/condition/immobilized">Immobilized</a>, but it can&#x27;t move beyond the reach of the frog&#x27;s tongue. A creature can sever the tongue with a Strike against AC 13 that deals at least 2 slashing damage.
This deals no damage to the frog but prevents it from using its tongue Strike until it regrows its tongue, which takes a week.
