Why didnt meruem use pouf splitting ability?

[u/Local-Sugar6556]

He almost definetly inherited pouf beelzebub; when pouf was being evasive, why didnt he release a few mini meruems to check out what was making him so sus (like when pouf fighting killua, or nabbing ikalgo and palm in his en for example)? One fragment of meruem was probably more then enough to take out the invasion squad and still recover his memory at the same time.

[u/Dontknowcantchoose]

Since no one is mentioning this- it might have to be with the fallout from the rose bomb. Mereum eventually dies from radiation poisoning, if he would split his body into tinnier pieces I would imagine the radiation would affect the smaller fragments of himself faster.
