where it's all Cretacia, all the time!

ROCKY: And boy, do we have some news for you!

Today, Hegan gave us a ride over to Mount Oblivion,

because it was acting like a real hot-head.

TINY: I wonder who made it mad.

MAZU: That's not the way volcanoes work, Tiny.

A volcano is basically just a hole in the ground.

BILL: Sorry, Mazu,

but does Mount Oblivion look like a hole to you?

MAZU: Here, let me explain.

There's all this hot liquid under the Earth called magma.

When too much magma builds up

it shoots out through ruptures in the ground.

The hot rocks and liquid that come out are called lava.

When the lava cools,

it builds up on the sides of the hole,

and eventually forms a volcano.

ROCKY: Wow, cool!

TINY: No, hot!

BILL: As we flew by,

it sure seemed like Mount Oblivion

was under a lot of pressure.

ROCKY: I told Hegan to drop me off

so I could get a better look.

TINY: Of course we couldn't let Rocky go alone.

MAZU: It wasn't safe!

ROCKY: What are the chances

that just at that moment Mount Oblivion was gonna...

ALL: Erupt!

BILL: We had to get outta there, fast!

(Screaming)

(Screaming)

BILL: I didn't mean this fast!

ROCKY: Adventure! Ah, ha-ha!

(Screaming)

MAZU: This is during the Cretaceous period

when scientists think that volcanoes were pretty active!

TINY: Which keeps us pretty active!

MAZU: Fortunately, not all volcanoes are active.

Some are dormant,

which means they haven't erupted in a long time,

but could erupt again.

And then there are extinct volcanoes.

They're the ones that are done erupting.

BILL: Why can't we live next door

to one of those extinct ones?

MAZU: We knew that the lava would cool eventually...

ROCKY: But luckily Hegan came to save us before that!

BILL: 'Cause who wants to wait on a rock until "eventually"?

MAZU: The good news is that volcanic eruptions

provide rich nutrients to the soil.

Cretacia will bounce back!

TINY: And have beautiful plants and flowers once more!

ROCKY: There you have it, folks.

Big news coming your way from Mount Oblivion today!

BILL: Let's hope tomorrow's news is a little less explosive!

(All laughing)
