Dinotopia Walkthrough:

(i) Search beach thoroughly and pick up any items (important to get 
conveyor belt (looks like a towel & found to left of path through 
jungle). Enter ship & get crowbar & candlestick. Click crowbar on clam 
shell (to open clam the mouse click must be on exactly the right spot on 
the clam - very frustrating).

(ii) Head up path to first village (Hatchery) and click on door near 
where 2 children are standing. Talk (click) to old woman & get dinosaur 
ABC. Open it and use it to decipher all letters of the alphabet (write 
them down to translate messages later). You will now be able to click on 
people & dinos & understand them. Go to first house (windmill) and use 
conveyor belt on gears. Show people your sister's picture & be told to 
go to next town - Pumicetown. Talk to dinosaurs attached to carriage 
(they will mention a gramaphone) and get transported to Pumicetown.

(iii) Pumicetown - Play cards with dino in the fairbooth (put an object 
in the offer box eg. candlestick). If you win you get a metal item. Find 
stairway to smithy and melt metal item. Pour metal item into key mould, 
cool & get key (you will get verbal instructions if you forget to use 
gloves, tongs, etc). Talk to everyone & show picture of your sister & 
you will be told to go to Waterfall City. Go back to Hatchery first via 
dino carriage & then walk to beach.

(iv) Beach again - click key on trunk to open it & get time-piece. Then 
back to carriage to go to Waterfall City.

(v) Waterfall City - You can waste a lot of time here wandering around 
so look for areas where blue octagonal squares are part of the pavement 
(indicates a place you can enter). First find museum after meeting dino 
friend. It is across the bridge (S) and then far right. Talk to curator 
& enter slide room. Clean slides & look at them in projector. Talk to 
curator again about the gramaphone - he will mention a gear, a trumpet & 
a recording device. He gives you the base model.
Find building across bridge (N) you can enter. Dino outside window will 
sing a series of musical notes. Repeat first note on xylophone and then 
each additional note. If you succeed you get the recording device & a 
nice fanfare on exiting the building. Head back across bridge (S) and 
then West to find glasshouse. Enter & talk to dino then water flower 
with can. Cut large trumpet flower with shears. Head back to carriage & 
go to Pumicetown.

(vi) Pumicetown again - Back to smithy & melt key. Then pour into gear 
mould, cool as before. Click on all components of gramaphone - base, 
recording device, gear & trumpet. Give gramaphone to dinos pulling 
carriage & a new location appears on the map - Old Ruins. Go there.

(vii) Old Ruins - find big dino & talk to him. He will give you his 
insignia (looks like tusks) & ask you to find his nephew in the World 
Beneath. Enter ruins and find hole in wall near back & to the East. 
Follow path to stairs going down. Enter. After walking underground you 
come out on mountain plateau. Talk to woman & stand on carpet. Wait 
until flags stay still for just a moment (in downward position) & then 
walk off cliff. Never fear if you have timed it right you will end up on 
the back of a flying dino (your next method of transportation). Fly to 
Savannah.

(viii) Savannah - talk to dino at entrance to factory. Walk on metal 
paths inside factory or just slog across the muck to find entrance to 
machine room at rear near far left. Enter & pull levers to get the same 
sequence of musical notes as previously done at Waterfall City. You will 
head downwards & get a scroll. Exit factory. Fly to Treetown

(ix) Treetown - To save time wander around & find Fireweed (near canal - 
approx. center). Then find moss on tree - it has a yellow cloud of bees 
on it. Go to next tree (in front) and click on sap collecting cup - sap 
pours out & cloud of bees moves from moss to cup. Now get moss. Climb 
ladder into tree and wander around (to the right) to find big dino. Talk 
to him & show him all pictures. He has a cough & sore throat. In front 
of him is a flask. Click on moss then on flask (now you can pick it up). 
Then click fireweed on flask - cough & sore throat medicine. Clicking 
the potion on the big dino then didn't work for me but clicking it on my 
dino friend did (weird!!!). The big dino will give you a prism. (Note: 
to find out about the description & use of important items like the 
prism click them on your little dino friend). Exit & fly to Alpine.

(x) Alpine - It is not necessary but you can go to the nearby hut and 
trade any unimportant item for a pick. Climb the mountain but take care 
to cross the mountain slides by the ice bridges. Enter monastery and 
talk to monk. He will give you a red sunstone. Exit and for fun slide 
down the mountain. Fly to desert.

(xi) Desert - Talk to old dino at oasis or far NW of desert where there 
are buildings. He wants you to find another dino & bring him home. Go to 
far NE to find him and then he will follw you back NW. Enter building, 
climb ladder, go E, descend ladder to another beach. Examine sundial. 
Put prism on central column of stones. Now click scroll on you to read 
it & arrange central stones of sundial according to the scroll. Click 
also on SW and SE outer stones to light them. Decipher wording on scroll 
'give your time to another'. Give timepiece from trunk to old dino and 
suudenly a hole appears in the sundial. Descend ladder and enter 
submarine.

(xii) Sub - remove old used sunstone and replace with new one from monk. 
Click on levers to right of sub - cutscene. Interface changes to arcade 
sequence now. Hold mouse button down and drag to descend in sub. Go to 
left of screen and follow underwater passages continuously to the W 
across several screens as far as possible. May need to move fish, sharks 
& jellyfish with lever to far left (electricity) or next lever (smoke). 
Then ascend in sub (don't ever exit as you will find yourself back at 
sundial and will need to repeat sub sequence again) until you reach 
surface & a new temple. Move sub near open doorway & click on doorway. 
Cutscene follows with sister & dino's nephew in World Beneath. Then you 
click on one of two choices to return to the normal world or stay in 
Dinotopia. The latter seems the obvious choice leading to a final 
cutscene. That's it folks!!

All in all quite a fun game for a few hours of expensive gameplay but 
the interface is a real pain until you get used to it. Many of the 
objects & much of the conversation lead nowhere & must have been added 
for background. Sound is poor & difficult to distinguish - you will need 
to listen carefully. Good fun for junior adventurers - nothing risque, 
no violence, no bad language.
