Where do I find all the Eggos?
According to posts in this megathread, the only two Eggos that aren't obtained from defeating bosses are the one in Wheeler's refrigerator and the one you find by breaking a wall in Bradley's Big Buy store.
- ALL EGGOS – 1-6 by defeating bosses
- 1 In the Wheelers Fridge
- 1 In the cracked wall in the big buy store
The only two Eggos not obtained from defeating bosses (1-6) are the one in the Wheeler's fridge (7) and the one found by breaking the wall inside Bradley's Big Buy store (8).
Based on the second quote, it looks like the Eggo you're missing is the one behind the breakable wall in the Big Buy store.
