Talk:Swap Frog

ok here is the question..

can I return the Swap Frog itself for its third effect? the "return one monster you control to its owner's hand. you can normal summon another frog this turn" effect.

And after this, do i have to summon the frog? can i just return one monster and forget about the summoning?

one more thing.. it says "Normal Summon". This could be a Normal Summon or Set. If my opponent Sets the monster, how do i know it is a frog monster? Should it be Normal Summoned only? thanks everyone!
