To get your skates on means to hurry up, so the speaker is telling the other person to hurry up so they can find the frogs.
Context: Well, go and do it then, but hurry up, otherwise we 'll never find those frogs.
Hypothesis: Well, go and do it then, but get your skates on, otherwise we 'll never find those frogs.

Is the hypothesis incorrect? (Yes, no, or unknown)?
