Oreo? No... Lollipop, maybe?

Question

Since 2009, Android's version code names have been confectionery-themed. Android 1.5 is Cupcake, Android 1.6 is Donut, Android 2.0 is Eclair, etc.. In fact, the version names are alphabetical!

C -> Cupcake
D -> Donut
E -> Eclair
F -> Froyo
G -> Gingerbread
H -> Honeycomb
I -> Ice Cream Sandwich
J -> Jellybean
K -> Kitkat
L -> Lollipop
M -> Marshmallow
N -> Nougat
O -> Oreo

In order:

Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, Jellybean, Kitkat, Lollipop, Marshmallow, Nougat, Oreo

Challenge

Write a program/function that takes a letter from C to O and outputs its respective Android version code name.

Specifications

• Standard I/O rules apply.
• Standard loopholes are forbidden.
• You can choose to either support lowercase input or uppercase input or even both.
• The output may be in title case (Cupcake) or completely lower case (eclair). Ice cream sandwich may be capitalized however you like. (I didn't expect it to cause so much confusion...)
• This challenge is not about finding the shortest approach in all languages, rather, it is about finding the shortest approach in each language.
• Your code will be scored in bytes, usually in the encoding UTF-8, unless specified otherwise.
• Built-in functions (Mathematica might have one :P) that compute this sequence are allowed but including a solution that doesn't rely on a built-in is encouraged.
• Explanations, even for "practical" languages, are encouraged.

Test cases

These are uppercase and title case.

Input   Output

F       Froyo
I       Ice Cream Sandwich
J       Jellybean
N       Nougat
G       Gingerbread
L       Lollipop

In a few better formats:

F, I, J, N, G, L
f, i, j, n, g, l

F I J N G L
f i j n g l

Bash + Core Utils 131 128 122 117 bytes.

The script is encoded as Base64 because it contains special (weird) characters.

Accepts the Android codename letter only in lowercase as its first positional parameter. Returns the full codename also in lowercase.

Explanation:

#�Q��������s�X����!�>0�������`N`x������~$�^@7�D�    ��X5�0'�D�� 
base32 $0|tr 'A-Z47
' 'a-z
 '|grep ^$1

• The first two lines are the binary blob with the data (see a the end of the answer for more information). The first line is empty, to avoid problems with Bash, as otherwise it may think that is being fed with a binary file.
• base32 $0 encodes the script contents with Base32, with the default line wrapping of 76 characters.
• tr 'A-Z47\n' 'a-z\n ' (note that the \n is written as a literal newline) will lowercase the input and replace 4, 7 and \n by \n, space and space respectively.
• grep ^$1 will output the lines matching the string provided as first argument to the script.

---

Binary data

This octet stream was forged so it doesn't contain newlines and when it's decoded with Base32 as per RFC 4648, the resulting string is the list of Android codenames (using 4 as item delimiter and 7 to replace the space character). Among its peculiarities, it begins with a newline character and a hash (#) so it behaves as a comment and, therefore, isn't executed by the interpreter.

Also, the default line wrapping to 76 characters of this Base32 implementation helped me a byte, as I reordered the items to use the line break as one of the Ice cream sandwich spaces.

---

Also, and going a bit off-topic, I think that Google shouldn't indirectly advertise commercial products in the Android codenames.

Explanation

Implicit input of uppercase character string U.

A compressed string (everything between the backticks) of the names, separated with an f and without their first letter is split (q) into an array on f.

Within that array we get the element at the index (g) of Us character code. (Yay, index wrapping!)

We append that to U and implicitly output the resulting string.

• Each of the +.../...+...=7?6{...} compares the input to each ASCII value (C, D, E, F, etc) and executes the code within {...} if they are equal.
• Each code block ({...}) prints the rest of the name (the first character is already printed).
