Piñata Vision barcode/Choclodocus egg card
From PinataIsland.info, the Viva Piñata wiki
Looking at the ID table, several egg cards are missing. Based on the alphabetic order for the egg cards and the missing IDs, there's likely an Egg_dinosaur_208 card that hasn't been released.
Here's the relevant snippet from the ID table.
207 C4 CB76D954B86F82A4 Vision_Single_PlaceTag_Egg_deer_207.jpg 208 ?? C6?? Dinosaur egg?? 209 FF F1706B687463A38F Vision_Single_PlaceTag_Egg_dog_209.jpg
Based on the sequence of the obfuscated sets, it's possible that the Choclodocus egg card is a C...6 card.
The goal of the project is to find a similar obfuscated card, and change its ID bits to 208, to see if a Choclodocus egg card can be scanned. Naturally, other bits (checksum or non-checksum bits that produce a net zero sum) need to be changed too, so the card remains valid.
Among the possibilities, a good candidate is the Egg_lion card, since it requires the least manipulation.
- 0201 Egg_chameleon 201 -> 208. Flip ID bits 0, 3, 4
- 0218 Egg_firefly 218 -> 208. Flip ID bits 1, 3, 4
- 0248 Egg_lion 248 -> 208. Flip ID bits 3, 5
- 0287 Egg_sheep 287 -> 208. Flip ID bits 0, 1, 2, 3, 6

ID bit 5 bit difference results
Comparing pairs of nearly identical cards whose ID values differ by 32. The sole difference that these cards have are with bits 12 and 13. Setting bits 12 and 13 to 1 sets ID bit 5 with a zero-sum change to other card bits.
Since ID 248 is a valid C6 card, clearing bits 12 and 13 should produce a valid C6 card with an ID of 216 (C6FEF696AB02C4B6). Unfortunately, there is no such item.
