A Thwack Totem is a variety of Thwack found in the Thwomp Caverns inside the Thwomp Volcano, in Mario & Luigi: Partners in Time. A Thwack Totem is created when several Thwacks decide to merge into one being. Each individual Thwack will hop on top of another, building a Thwack Totem that sprouts two arms and two legs. Thwack Totems can only be battled by Baby Mario and Baby Luigi.
In battle, a Thwack Totem attacks by dispatching its individual Thwack segments to attack the Baby Mario Bros. First, a Thwack Totem may launch itself in the air with rocket boosters, then break apart into individual Thwacks. Each Thwack would then fall to the ground, creating seismic waves that the Baby Mario Bros. must avoid by jumping. As with individual Thwacks, the color of a Thwack matches the color of the Baby Mario Brother it will attack. A Thwack Totem may also perform a spin attack. As the totem spins, individual Thwacks fly off and would be sent careening into a brother. These Thwacks can be blocked with a hammer swing.

Thwack Totems will not be damaged by first strike attacks by the Baby Mario Bros., even though a damage amount is displayed. The reason being is that the battle starts out with four Thwacks, and if a first strike attack does not defeat them, they immediately assemble before the Baby Mario Bros. can make another move and thus, negates the first strike damage.
