Frustrated by a French Frog

I was surprised when I found a house on my path today! What kind of wizardry is this?!

A new house that landed on my path!Inside, I found Cousteau the French frog. So Frobert left, only to get replaced by another frog? Give me Frobert back, I don’t want this thing. He should be exploring the bottom of the sea instead; I’ll help him out by dropping him in the ocean.

Cousteau: Hey! So you're from Forest, right?Saturday night is K.K. night, and the singing dog performed Steep Hill for me tonight. I always enjoy this song.

K.K.: All right, get ready to dig the riffs on this ditty: Steep Hill.Twiggy then asked me to make a delivery to Fang, and I did…with just five minutes to spare. The gift was a bad plaid shirt.

Fang: Well, well, if it isn't the bad plaid shirt I asked for.I returned to Twiggy to tell her the delivery was complete. She rewarded me with a backyard lawn.

Twiggy: I'll pay you back someday, Jeff! Just let me know whatcha need!
