モリモリ島のモーグとペロル, Mogu&Perol, Morimori Shima no Mougu to Peroru

Mogu consistently prepares delectable meals, yet Perol seems to be consuming an excessive amount. One day, while gathering berries for a cake, Perol eats some raw from the bush and finds them sour. He suspects Moog of tricking him and ends their friendship. Despite this, Perol withdraws but becomes increasingly withdrawn, causing Moog to miss his companionship.
