Sorry, I forgot that creatures weren't permanents.
"Each turn
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
is generated for each frozen card."
"When the last card unfreezes,
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
is produced."
If it was indeed intended to trigger off every unfreezing then I must have misunderstood it. That seems kinda broken with squids though.
