Yep, same as Cheetos now. Were around in the late 70's though when Happy Days was popular. Blue bag with stars and a sticker of a HD character inside.

When our local Primary School was being upgraded with new buildings I found an empty packet of Fonzies in an old garden. It bought back so many memories and who knows it may be a packet that I once ate from.

I loved rushing hm from school, diving into the pantry and grabbing the Fonzies to share with my best friend Natalie -i miss them both so so much xo

They still have Fonzies here in Italy! I see them all the time at the supermarket!

The companies in Australia that made a snack called Twisties (goes back to around 1952, Melbourne) also started Fonzies around 1987, and production spread to the UK and some South Pacific island countries. No reference to the "Happy Days" character is made. The name may have been simply lifted, as "Happy Days" reruns aired in some foreign markets. One bag of Fonzies is selling online for two British (or Australian) pounds. I think the UK is now in the Euro cash system.
