Grossest Candy #10 - White Chocolate Maggots

Why are these so gross? I think its because they are white and
therefore actually look like maggots - and maggots are gross.
Really gross. I get the willies just thinking about maggots and the
rotting flesh/garbage/food they go along with. Plus, these are made
of white chocolate, which is gross too.
Grossest Candy #9 - Hose Nose

This is a candy dispenser that looks like a nose that you strap to
your face. It oozes candy slime and they encourage you to stick out
your tongue and catch the drips from the nose. Some of the slogans:
Itsnot what you think, candy slime filled, drippy, and
catch it on your tongue. Yes, snot is gross and this candy
encourages you to eat candy snot.
Grossest Candy #8 - Sour Flush Candy

The candy in this is nothing special - its powdered candy (like
Pixy Stix) and a lollipop. Its all about the presentation though.
The powdered candy comes in a realistic plastic toilet and the
lollipop is flat on the end so it looks like a toilet plunger. Lick
the plunger then dip it into the toilet to get some candy on it.
Yum!
Grossest Candy #7 - Harry Potter Cockroach
Clusters

At #10, we had white chocolate maggots. Here at #7 we have
cockroaches (and this isnt the last bug well see on the
countdown). These are Harry Potter Cockroach Clusters. Each
Cockroach has a juicy gummy underbelly and is covered with a
crunchy candy shell that has candy cockroach wings! Each cockroach
is about 2 inches in length and 1 inch wide, so theyre also a
great candy to use to scare your friends
Grossest Candy #6 - Fear Factor Candy

used to watch Fear factor all the time and the best (worst?) part
was watching them try and eat those gross things. Now, you can have
all the fun of the Fear Factor eating contests at home with Fear
Factor Candy. There are a ton of them too. Some of the
grossest:
- Fear Factor Lollipops (seen above): Chicken Foot (lemon
flavored), Pigs Snout (bubblegum flavored), Sheeps Eye (black
cherry flavored), and Cows Heart (spicy cinnamon flavored)
- Fear Factor Gummy Frog Legs: Gummy sour apple frog legs that come
with crunchy candy bones and gooey red dipping sauce
- Fear Factor Slimy Gummy Octopus: This super sweet slimy gummy
octopus is swimming in sour ooze. The head of the octopus is lemon
and the tentacles are blueberry
- Fear Factor Gooey Globs: Liquid-filled gummy balls in 2
incredibly creepy designs: Sheep Eyeballs (Mango) and Coagulated
Blood Balls (Cherry)
-Fear Factor Cockroach Bites: Cola-flavored gummy roaches with
crunchy icing shells - packed in sets of two
Grossest Candy #5 - Poop Candy

Poop is gross. Just ask anyone who has had to change a babys
diaper. Once youve done that, youll never look at poop in the
same way. Above, you see a prime example of poop candy - the
Chocka-Ca-Ca diaper. The diaper comes in blue, pink, or yellow, but
each one comes with a luscious chocolate turdle inside.
Yum!
Other examples of poop candy include the pooping candy dispensers
that are so popular around holidays. Moose, chickens, deer, cows,
pigs, kitties, snowmen, penguins, easter bunnies, and even Santa
himself can be had in pooping candy dispenser form. None of those
tops the Chocka-Ca-Ca though.
Grossest Candy #4 - Bertie Botts Every Flavor
Beans

Anyone who wonders how these Harry Potter jellybeans could make our
Top 10 Grossest Candy list has not tried these. They are
disgusting. I reviewed them a while back and it still brings back
bad memories for me. The flavors: Bacon, Black Pepper, Booger,
Dirt, Earthworm, Ear Wax, Grass, Rotten Egg, Soap, and Vomit. Some
of them arent too bad, like Black Pepper. Some of them are
horrible: Earthworm, Rotten Egg, Earwax, and Vomit.
David and I actually both voted these to be #1 on the list but
Victoria listed these much lower - if she had ever tried them I bet
these would have taken the top spot. Try them and youll see that
they deserve a spot on anyones Top 10 Grossest Candy list.
Grossest Candy #3 - Ear Wax Candy

Yes, ear wax candy. Its a plastic ear filled with a fruity
jelly-like candy that resembles ear wax. It even comes with a
plastic swab to use to dig out the candy. I dont know why they
chose to make the ears pink though - if youre going gross, you
should go all out - they definitely should have made the ears
flesh-colored.
Grossest Candy #2 - Candy With Real Bugs

I remember getting a lollipop once as a promo item at a (non-candy)
convention and it had a worm inside (it was supposed to). I never
tried it. I let it sit for ages until I finally just threw it away.
I couldnt bring myself to try it. You know a candy has to be gross
for me not to even try it.
There is an amazing amount of candy with real bugs in it. Hotlix is
probably the most well-known maker of candied bugs but you can find
them made by lots of companies. You can get tequila lollipops with
a worm inside, Cricket Lick-Its lollipops with a real cricket
inside, lollipops with a real scorpion inside (yeah, I know a
scorpion isnt a bug), Ant Candy which has real ants and looks like
a miniature ant farm, and of course, you can get all manner of bugs
covered in chocolate. No matter what kind of candy and no matter
what kind of bugs, candy with real bugs in it is gross. (Look for a
full review of Hotlix candies coming soon).
Grossest Candy #1 - Lick Your Wounds Candy
Scabs

I first found the Candy Scabs a few weeks ago and knew I had
stumbled onto a candy that is really and truly gross. They come on
an adhesive bandage replica that sticks to skin and encloses a
candy scab for licking so you can keep some candy on you (hidden)
for licking any time. I predict they will be a huge hit with kids
across the country (and parents and adults will despise their very
existence). I know I will be picking up a box, even if they are
gross.
