I'm on Island #11, but it seems like I'm missing so many items.
1. SKULL ISLAND - I have finished, but I need to "sacrifice 10 bones for the idol" and I only have 7 left. I have looked everywhere. I have defeated everything. I can't find anymore.
2. FROZEN VALE ISLAND - "30 shells to unlock chest." I only have 28 and have looked everywhere.
3. 7 COINS - I have 6, but I'm not sure if I've missed the 7th or I haven't gotten to it yet.
4. I only have access to 11 buildings, the last being the LABORATORY. Should I have more?
Thanks!
