Decode Marvin the Monkey's secret message by following the letter substitution clues.

Let's solve the "Monkey Message" puzzle step by step.

---

🔍 Step 1: Understand the Code

We are given a message in a speech bubble:

```
ZMO L
QMCA M
KMJMJM
RMJBLUFQ?
```

And a list of decoding rules:

- Change all Ms to As
- Change all Js to Ns
- Change R to S
- Change A to E
- Change U to W
- Change K to B
- Change B to D
- Change C to V
- Change Z to M
- Change O to Y
- Change Q to H
- Change F to C
- Change L to I

(Note: Some letters appear multiple times — like M, J, F, etc. — so we must apply all applicable rules.)

🔁 Step 2: Apply the Rules One Letter at a Time

We'll go through each letter in the message and replace it according to the rules.

#### First Line: `Z M O L`

- Z → M (from rule: Z to M)
- M → A (M to A)
- O → Y (O to Y)
- L → I (L to I)

So: M A Y I → "MAY I"

---

#### Second Line: `Q M C A M`

- Q → H
- M → A
- C → V
- A → E
- M → A

So: H A V E A → "HAVE A"

---

#### Third Line: `K M J M J M`

- K → B
- M → A
- J → N
- M → A
- J → N
- M → A

So: B A N A N A → "BANANA"

---

#### Fourth Line: `R M J B L U F Q ?`

- R → S
- M → A
- J → N
- B → D
- L → I
- U → W
- F → C
- Q → H
- ? stays as ?

So: S A N D I W C H ? → "SANDWICH?"

---

✔ Final Decoded Message

Putting it all together:

> MAY I HAVE A BANANA SANDWICH?
