Fattered Monstrocity - needs more HP or something added to it [suggestion]

love the Fattered Monstrocity mob design, but it feels odd to have such a large mob go down like a skeleton. my ideas:

-give it 10/20x the current HP
-keep current HP but make it spawn bunch of those ticks on death (also cleansed mob type), juts smaller and faster (nice nightmare fuel for anyone that ever saw tick mama giving birth)
