Spot the frogs puzzle

Thank you so much for all your lovely comments, stars and faves for yesterday's 2000th Blip, you're absolutely the best ! I'll try to thank you all personally within the following days but in the mean time please accept this puzzle image as a thank you note, there are 4 frogs in this rather busy green image :-) Can you spot them? I have to sneak up to them to catch and capture them, as soon as they spot me the live ones will jump back into the pond, but I managed to catch them all the same :-)

I'm afraid between thanking and replying I won't have time for the Abstract Thursday comments and results today, so I'll have those tomorrow !
