Plot twist: they blocked their own, to whitewash, a small red dot – this is a literal description of how Yashur was pierced through with an boarding saber (in the scale of the Universe, the dot is quite small), and to top it off, Yashur forgot to send the Night Defense.

I'm still leaning towards the idea that Ples is the monkey.
The Mafia might not have blocked for two reasons:
1) They were afraid to block Kraken (which is kind of stupid, what if he retaliates against them, unless the Mafia has immunity))
2) They didn't want to whitewash someone with their block.

Or the monkey ended up with some inactive player, who simply didn't send the Night Defense to the Master.
