Is my pacman ok?

[spearhead]

Hi guys, just changed my pacman substrate today and it got its weekly soak, however i realise there is this dark coloured patch on its legs, anybody has any idea what is it? Is it dangerous? Sorry for the lousy pic, cause i was holding the frog one hand and my other hand had to use my phone to take the photos. I am pretty sure the bump happened within this week as i check the frog once a week.
