The word 'Schnecke' (snail) has very different meanings. The context always makes clear what is meant: biology and garden (animal), bakery (pastry), medicine (inner ear), or a personal description (slow person).
Beim Bäcker nehme ich eine Nussschnecke.
At the bakery, I'll take a nut roll.
The expression 'im Schneckentempo' (at a snail's pace) is often used to express that something or someone is moving extremely slowly. It comes directly from the slowness of the animal.
Der Verkehr bewegte sich nur im Schneckentempo vorwärts.
Traffic was moving forward only at a snail's pace.
When 'Schnecke' (roll/bun) means a pastry, it is often part of a compound word that describes the filling. Typical examples are 'Zimtschnecke' (cinnamon roll), 'Nussschnecke' (nut roll), or 'Mohnschnecke' (poppy-seed roll).
Ich hätte gern eine Mohnschnecke und einen Kaffee.
I'd like a poppy-seed roll and a coffee.
In medicine and biology, 'Schnecke' (cochlea) refers to a specific part of the inner ear. This meaning occurs almost only in specialist texts or at the doctor's.
Die Schnecke ist für das Hören von Geräuschen entscheidend.
The cochlea is crucial for hearing sounds.
Calling someone a 'Schnecke' (slowpoke) is colloquial and often intended to be slightly derogatory. It expresses that the person is perceived as very slow.
Na los, du Schnecke, der Bus wartet nicht!
Come on, you slowpoke, the bus won't wait!

'Rakete' and 'Schnecke' form a colloquial contrast here. A person or vehicle that is 'eine Rakete' is very fast. A 'Schnecke', on the other hand, is a very slow person; this can also sound derogatory. So the contrast does not work with the normal meaning of a space rocket or an animal, but with the figurative meaning related to speed.

Beim Aufräumen ist mein Bruder manchmal eine richtige Schnecke.
When tidying up, my brother is sometimes a real slowpoke.
Auf dem neuen Fahrrad ist Tom eine echte Rakete.
On his new bike, Tom is a real rocket.
