[Courage is only something Pippin has when he's not thinking about it. But being taunted by an elf helps him not thinking about it so much, so he starts splashing out-- at least until the temperature causes him to shiver and hug himself.]

Oohoohoo, it is colder further out!

[Getting Legolas back for the splash seems to have momentarily taken backseat to getting used to the water. Key word there may be "seems".]
