After dealing with those fellows, Chén Nuò and Whimsicott set off along the coastline, heading in the exact direction Feebas had taken.
The advantage of walking this way was that if Feebas turned back, she would easily spot him near the shore. Strolling along the coast, Chén Nuò only hoped to find Feebas as quickly as possible!
As for why he brought Whimsicott along? Naturally, to ensure safety—if someone launched a sneak attack, it would be far too late to release a Pokémon then!
