Cool!!!
Just confirmed that /mov command works on:
Plant_Beast_01 (Bladegrass)
Plant_Beast_02 (Razorvine
Plant_Beast_03 (Blackrose)
Plant_Beast_04 (Deathblossom)
Plant_Beast_05 (Herder)
Giant_Plant_Monster (Thorn Monster)
Mushroom_Beast_01 (Fungoid)
Mushroom_Beast_02 (Deathspore, Fungoid)
Mushroom_Beast_03 (Deathcap, Fungoid)
Giant_Mushroom_Monster (Stropharia Monster)
Croatoa_Fir_Bolg_Boss (Streng)
Croatoa_Fir_Bolg_Lieutenant (Guardian)
Croatoa_Fir_Bolg_Minion (Soldier)
Croatoa_Fir_Bolg_Monster (Eochai Monster)
Pumpkin_King (Halloween Event Monster)
Pumpkin_Minion (Streng)
After you've spawned them, make sure they are where you want them because once you've made them do the /mov t_spawn_rooted command they become unselectable.
