[Icy Onslaught] Rumbling with Rimos

Jade has something to tell you. What could it be?

While Jade looks for the El Nath Unmeltable Ice Shard you requested, the earth begins to quake and a terrible cry can be heard.
These constant disruptions are driving the townspeople crazy. Defeat Rimos and put an end to its tantrum.
You should bring Jade proof that you defeated Rimos.
(Defeat Rimos monster and collect its Rimos Shorts.)
NOTE: Any Rimos from any Icy Onslaught invasion map will qualify.
