It seems that Mizuko doesn't realise that the more weight belts she put on, the faster she'll sink down to the bottom of the pool. She learnt that the hard way.

Looks like Sakura has gotten herself in a bit of a pickle. She was tied up and dropped into the bottom of the swimming pool. Now she's struggling to free herself while glaring at her captive.

It seems that Yang was caught in a windy weather, getting dragged backwards by the Undertow. She caught a metal pole and held on til the undertow is over.
