A frog's eyes grow inside its mouth.
The claim regarding a frog's eyes growing inside its mouth is incorrect. While frogs do use their eyes to assist in swallowing by retracting them into their heads, there is no evidence to suggest that their eyes literally grow inside their mouths. This appears to be a misunderstanding or misstatement about how frogs use their eyes during eating.

A frog's eyes grow inside its mouth.
Frog eyes do not grow inside their mouths. Instead, frogs retract their eyes into their heads to help push food down their throats when swallowing, as they lack the muscles to chew. This biological feature is a functional process rather than actual growth inside the mouth.
