Durapurl

Durapurls' are pale-coloured oysters that appear in Mario & Luigi: Dream Team. In the field, Durapurls will wander around aimlessly until they spot Mario and Luigi, where it will then chase after them briefly.

In battle, Durapurls may approach a Bro. and flicker its shell closed, then open three times, on the third time, the pearl inside shooting out of the oyster and into the approached Bro, who must counter by smashing the pearl into the sand before him at the instant the pearl shoots out to daze it, and following that up with several swings of the hammer to deal maximum possible counter-attack damage.

Durapurls may also let their pearl out to roll towards a Bro., to then roll into the Bro. from both the front and behind several times, which must be dodged by jumping over or on to the pearl until the attack ends. As the shell of the Durapurl is hard, more damage can be done through counter-attacks as those allows Mario and Luigi to hit its weak point; the live pearl inside.
