It has been a long time since you took the boys back to the park.
You told mugs to not go back to the lake that was right by the park, you didn't want him to ger sick again or worse.

Mugs promised that he wont do it again little did you know he had his fingers crossed.
As you took the boys to a very full park it wasnt hard for mugs to slip away as there was so many kids.

Mugs went back to the lake and hopped on some rocks "hello...? Octopus lady??" Mugs yelled out, there was no reaction. Just empty waters, mugchild calls some more before he saw purple at the rocks again, climbing up the big rocks he sees the girl again, she has pretty blue eyes, that same octopus on her head, and a scar on her arm. She looks at mugs with a shocked look, surprised that the boy in blue came back.

"Um....hi" mugs said shyly with a wave, the girl didnt say a word but mimicked the wave "im mugs whats your name?" Mugchild said and still received no reply "can you talk?" Still no reply, she just looked at him with a deer in headlights look "dont worry im a friend!" Mugs said with a big smile which made the girl at ease, she returns the smile and dives into the water.

Mugs felt disappointed that she left so quick but the girl came back and held something up, it was a old necklace, probably someone threw in the lake. It almost looks bran new, covered in diamonds and a silver chain. "W-wow! Its so pretty!" Mugs said as if he has never seen anything so shiney, the girl put the necklace in his hands and as soon as she did they both hear you call for mugs.

The girl disappeared into the water and mugs quickly ran back without getting wet but dirty from climbing a small hill.

Mugs didnt get in trouble and gave you the necklace as a present, its your choice on what to do with the necklace.
