- The first game occasionally tricks you into jumping to the next screen... directly into a pool of water/lava.
- In the middle of Zoda's evil gloating, Mike jams bananas in his ears to drown him out. In the ending sequence of the second game a character mentions that he still has them in his ears.
Game: Your head is aching. You jam bananas in your ears.
- One of the sealed caves that Mike can blast open in the Wild West contains a giant chicken nugget. It tastes delicious!
- Several Non Player Characters comment on Mike's having bananas in his ears. This is also mentioned at the end of the sequel.
