Della got the berry from Jou only to watch Donald get slugged by the Magmar. Thankfully, being a water type meant that it didn't hurt too much. On the other hand, it made its headache worse.

"Aaaaugh, my head." he groaned, clutching his head, causing Della to stop and run back for the Psyduck.

"Oh, nonononono!" she cried out, slamming the berry down his beak. "No super psychic powers things!"

"Waaaaaaaugh!" Donald yelped as the headache got worse.

"Oh, no! Everyone take cover! Psychic duck with a headache!" Della shouted... tossing Donald at the villains as it went to use Water Gun, shooting the Psyduck skyward and drowning the villains as it did.

"DUCK AND COVER!" And she hid behind a table. "...that's not a psychic move."
