Tree Frog Print Stringy

I am very new to the world of 3D printing and I am looking for advice on how to improve the quality of my prints. I recently assembled a Prusa MK2 successfully (XYZ calibration suggested XY axis was skewed severely however after a few attempts I have not managed to correct this yet). After calibrating my bed height I successfully printed the PRUSA flat logo. I have now moved on to the Tree Frog and by all accounts the print came out well except for a stringy quality left by the hot end moving from one area of the frog to another. Looking through the forums has led me to believe this can be remedied by adjusting "retraction," could someone please walk me through how this is done? Until now I have only been commanding the printer using the LCD and what came on the data card. I printed the Tree Frog using the provided gcode and did not make any adjustments to settings for the printer. I have attached a few images of the final product. Any advice is appreciated!!

Hi,

I remember my first "half treefrog" that was a disaster (a paw move during the print and i stopped it...).

As you, i think that the gcode on the sd card was good but in fact it wasn't for my printer. I do not know why but as i checked absolutely everything and built a new gcode with my own parameters and solved the problem... so it's the one and only explanation (for me at least)...

First step i downloaded the treefrog stl file and put it in slicer. Then i played with all parameters of the printer (the "advanced > flow > bridge flow ratio" could explain your result). I decrease the movement speed too because i'm not hurry and the result seems to be better.

So try to modify the parameters of the gcode generator software.
